Class std.datetime.timezone.SimpleTimeZone

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

class SimpleTimeZone
  : TimeZone ;

It's primarily used as the time zone in the result of 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.


this (utcOffset, stdName)


hasDST[get] boolAlways returns false.
utcOffset[get] DurationThe amount of time the offset from UTC is (negative is west of UTC, positive is east).
dstName[get] stringTypically, the abbreviation (generally 3 or 4 letters) for the time zone when DST is in effect (e.g. PDT). It is not necessarily unique.
name[get] stringThe 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] stringTypically, 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.


dstInEffect (stdTime) Always returns false.
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 utcOffset as a Duration.
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.
