SimpleTimeZone

Represents a time zone with an offset (in minutes, west is negative) from UTC but no DST.

It's primarily used as the time zone in the result of std.datetime.systime.SysTime's fromISOString, fromISOExtString, and fromSimpleString.

name and dstName are always the empty string since this time zone has no DST, and while it may be meant to represent a time zone which is in the TZ Database, obviously it's not likely to be following the exact rules of any of the time zones in the TZ Database, so it makes no sense to set it.

Functions

dstInEffect bool dstInEffect(long stdTime): Always returns false.
tzToUTC long tzToUTC(long 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 Duration utcOffsetAt(long stdTime): Returns utcOffset as a core.time.Duration.
utcToTZ long utcToTZ(long 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.

Properties

hasDST bool hasDST [@property getter]: Always returns false.
utcOffset Duration utcOffset [@property getter]: The amount of time the offset from UTC is (negative is west of UTC, positive is east).

From TimeZone

name string name [@property getter]: 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 string stdName [@property getter]: 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.
dstName string dstName [@property getter]: 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 bool hasDST [@property getter]: 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.
dstInEffect bool dstInEffect(long 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.
utcToTZ long utcToTZ(long 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.
tzToUTC long tzToUTC(long 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 Duration utcOffsetAt(long 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).
