DateTimeZone represents a time zone.
A time zone is a system of rules to convert time from one geographic location to another. For example, Paris, France is one hour ahead of London, England. Thus when it is 10:00 in London, it is 11:00 in Paris.
All time zone rules are expressed, for historical reasons, relative to Greenwich, London. Local time in Greenwich is referred to as Greenwich Mean Time (GMT). This is similar, but not precisely identical, to Universal Coordinated Time, or UTC. This library only uses the term UTC.
Using this system, America/Los_Angeles is expressed as UTC-08:00, or UTC-07:00 in the summer. The offset -08:00 indicates that America/Los_Angeles time is obtained from UTC by adding -08:00, that is, by subtracting 8 hours.
The offset differs in the summer because of daylight saving time, or DST. The following definitions are helpful:
- UTC - The reference time.
- Offset - The amount of time a zone differs from UTC. This can vary during the year.
- Daylight Saving - The process of having two offsets each year, one in winter and one in summer.
- Raw offset - The base offset of the zone.
- Additional offset - The additional offset on top of the raw offset. This is typically zero in winter and one hour in summer in zones that apply DST.
- Actual offset - The actual offset that applies, which is the combination of the raw offset and additional offset.
For example, in 2018 Greece applied daylight saving. Throughout the whole year, the raw offset was +02:00. In winter, the additional offset was zero, while in summer the additional offset was one hour. Thus, the actual offset was +02:00 in winter and +03:00 in summer.
Note: Some governments, most notably Ireland, define daylight saving by describing a "standard" time in summer and a negative DST offset in winter. Joda-Time, like the JDK, follows a model for time-zone data where there is a raw offset all year round and a positive additional offset. As such, callers cannot assume that the raw offset is that defined by law for the zone.
Note: Some governments define a daylight saving time that applies for two separate periods. For example, the year might be winter time, then summer time, then a special time equal to winter time, then back to summer time before finally dropping back to winter time. As such, callers cannot assume that the raw and DST offsets directly correlate to summer and winter.
Unlike the Java TimeZone class, DateTimeZone is immutable. It also only supports long format time zone ids. Thus PST and ECT are not accepted. However, the factory that accepts a TimeZone will attempt to convert from the old short id to a suitable long id.
There are four approaches to loading time-zone data, which are tried in this order:
1. load the specific Provider specified by the system property org.joda.time.DateTimeZone.Provider.
2. load ZoneInfoProvider using the data in the filing system folder pointed to by system property org.joda.time.DateTimeZone.Folder.
3. load ZoneInfoProvider using the data in the classpath location org/joda/time/tz/data.
4. load UTCProvider
Unless you override the standard behaviour, the default if the third approach.
DateTimeZone is thread-safe and immutable, and all subclasses must be as well.

  - getOffset
```
public abstract int getOffset(long instant)
```
    Gets the millisecond offset to add to UTC to get local time.
    This returns the actual offset from UTC for the zone at the specified instant. If the method is called with a different instant, the offset returned may be different as a result of daylight saving or other government rule changes.
    
    Parameters:
    
    instant - milliseconds from 1970-01-01T00:00:00Z to get the offset for
    
    Returns:
    
    the millisecond offset to add to UTC to get local time
  - getOffset
```
public final int getOffset(ReadableInstant instant)
```
    Gets the millisecond offset to add to UTC to get local time.
    This returns the actual offset from UTC for the zone at the specified instant. If the method is called with a different instant, the offset returned may be different as a result of daylight saving or other government rule changes.
    
    Parameters:
    
    instant - instant to get the offset for, null means now
    
    Returns:
    
    the millisecond offset to add to UTC to get local time
  - getStandardOffset
```
public abstract int getStandardOffset(long instant)
```
    Gets the raw millisecond offset to add to UTC.
    This should be treated as an implementation detail. End-users should use getOffset(long).
    This returns the raw offset from UTC for the zone at the specified instant, effectively ignoring DST. If the method is called with a different instant, the offset returned may be different as a result of government rule changes.
    This method should be named getRawOffset() but cannot be renamed for compatibility reasons.
    
    Parameters:
    
    instant - milliseconds from 1970-01-01T00:00:00Z to get the offset for
    
    Returns:
    
    the millisecond offset to add to UTC to get local time
  - isStandardOffset
```
public boolean isStandardOffset(long instant)
```
    Checks whether, at a particular instant, the offset is raw or not.
    This method can be used to estimate whether Summer Time (DST) applies at the specified instant. As a general rule, if the actual offset equals the raw offset at the specified instant then either winter time applies or the zone does not have DST rules. If the actual offset does not equal the raw offset, then some form of Summer Time applies.
    The implementation of the method is simply whether getOffset(long) equals getStandardOffset(long) at the specified instant.
    This method should be named isRawOffsetInUse() but cannot be renamed for compatibility reasons.
    
    Parameters:
    
    instant - milliseconds from 1970-01-01T00:00:00Z to get the offset for
    
    Returns:
    
    true if the offset at the given instant is the same as the raw offset
    
    Since:
    
    1.5
  - getOffsetFromLocal
```
public int getOffsetFromLocal(long instantLocal)
```
    Gets the millisecond offset to subtract from local time to get UTC time. This offset can be used to undo adding the offset obtained by getOffset.
    millisLocal == millisUTC + getOffset(millisUTC) millisUTC == millisLocal - getOffsetFromLocal(millisLocal)
    NOTE: After calculating millisLocal, some error may be introduced. At offset transitions (due to DST or other historical changes), ranges of local times may map to different UTC times.
    For overlaps (where the local time is ambiguous), this method returns the offset applicable before the gap. The effect of this is that any instant calculated using the offset from an overlap will be in "summer" time.
    For gaps, this method returns the offset applicable before the gap, ie "winter" offset. However, the effect of this is that any instant calculated using the offset from a gap will be after the gap, in "summer" time.
    For example, consider a zone with a gap from 01:00 to 01:59:
    Input: 00:00 (before gap) Output: Offset applicable before gap DateTime: 00:00
    Input: 00:30 (before gap) Output: Offset applicable before gap DateTime: 00:30
    Input: 01:00 (in gap) Output: Offset applicable before gap DateTime: 02:00
    Input: 01:30 (in gap) Output: Offset applicable before gap DateTime: 02:30
    Input: 02:00 (after gap) Output: Offset applicable after gap DateTime: 02:00
    Input: 02:30 (after gap) Output: Offset applicable after gap DateTime: 02:30
    
    NOTE: Prior to v2.0, the DST overlap behaviour was not defined and varied by hemisphere. Prior to v1.5, the DST gap behaviour was also not defined. In v2.4, the documentation was clarified again.
    Parameters:
    
    instantLocal - the millisecond instant, relative to this time zone, to get the offset for
    
    Returns:
    
    the millisecond offset to subtract from local time to get UTC time
  - convertUTCToLocal
```
public long convertUTCToLocal(long instantUTC)

    Parameters:
    
    instantUTC - the UTC instant to convert to local
    
    Returns:
    
    the local instant with the same local time

```
    Converts a local instant to an actual UTC instant with the same local time attempting to use the same offset as the original.
    This conversion is used after performing a calculation where the calculation was done using a simple local zone. Whenever possible, the same offset as the original offset will be used. This is most significant during a daylight savings overlap.
    
    Parameters:
    
    instantLocal - the local instant to convert to UTC
    
    strict - whether the conversion should reject non-existent local times

                              boolean strict)
```
    Converts a local instant to an actual UTC instant with the same local time. This conversion is used after performing a calculation where the calculation was done using a simple local zone.
    
    Parameters:
    
    instantLocal - the local instant to convert to UTC
    
    strict - whether the conversion should reject non-existent local times
    
    Returns:
    
    the UTC instant with the same local time,
    
    Throws:
    
    java.lang.ArithmeticException - if the result overflows a long
    
    IllegalInstantException - if the zone has no equivalent local time

                               long oldInstant)
```
    Gets the millisecond instant in another zone keeping the same local time.
    The conversion is performed by converting the specified UTC millis to local millis in this zone, then converting back to UTC millis in the new zone.
    
    Parameters:
    
    newZone - the new zone, null means default
    
    oldInstant - the UTC millisecond instant to convert

  - isFixed
```
public abstract boolean isFixed()
```
    Returns true if this time zone has no transitions.
    
    Returns:
    
    true if no transitions
  - nextTransition
```
public abstract long nextTransition(long instant)
```
    Advances the given instant to where the time zone offset or name changes. If the instant returned is exactly the same as passed in, then no changes occur after the given instant.
    
    Parameters:
    
    instant - milliseconds from 1970-01-01T00:00:00Z
    
    Returns:
