Class `std.datetime.timezone.TimeZone`

Represents a time zone. It is used with SysTime to indicate the time zone of a SysTime.


						
				class TimeZone
				;

Constructors

Name	Description
`this` (name, stdName, dstName)

Properties

Name	Type	Description
`dstName`[get]	`string`	Typically, the abbreviation (generally 3 or 4 letters) for the time zone when DST is in effect (e.g. PDT). It is not necessarily unique.
`hasDST`[get]	`bool`	Whether this time zone has Daylight Savings Time at any point in time. Note that for some time zone types it may not have DST for current dates but will still return true for `hasDST` because the time zone did at some point have DST.
`name`[get]	`string`	The name of the time zone. Exactly how the time zone name is formatted depends on the derived class. In the case of `PosixTimeZone`, it's the TZ Database name, whereas with `WindowsTimeZone`, it's the name that Windows chose to give the registry key for that time zone (typically the name that they give `stdTime` if the OS is in English). For other time zone types, what it is depends on how they're implemented.
`stdName`[get]	`string`	Typically, the abbreviation (generally 3 or 4 letters) for the time zone when DST is not in effect (e.g. PST). It is not necessarily unique.

Methods

Name	Description
`dstInEffect` (stdTime)	Takes the number of hnsecs (100 ns) since midnight, January 1st, 1 A.D. in UTC time (i.e. std time) and returns whether DST is effect in this time zone at the given point in time.
`tzToUTC` (adjTime)	Takes the number of hnsecs (100 ns) since midnight, January 1st, 1 A.D. in this time zone's time and converts it to UTC (i.e. std time).
`utcOffsetAt` (stdTime)	Returns what the offset from UTC is at the given std time. It includes the DST offset in effect at that time (if any).
`utcToTZ` (stdTime)	Takes the number of hnsecs (100 ns) since midnight, January 1st, 1 A.D. in UTC time (i.e. std time) and converts it to this time zone's time.
`factory` (classname)	Create instance of class specified by the fully qualified name classname. The class must either have no constructors or have a default constructor.
`opCmp` (o)	Compare with another Object obj.
`opEquals` (o)	Test whether `this` is equal to `o`. The default implementation only compares by identity (using the `is` operator). Generally, overrides and overloads for `opEquals` should attempt to compare objects by their contents. A class will most likely want to add an overload that takes your specific type as the argument and does the content comparison. Then you can override this and forward it to your specific typed overload with a cast. Remember to check for `null` on the typed overload.
`toHash` ()	Compute hash function for Object.
`toString` ()	Convert Object to a human readable string.
