Class std.datetime.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 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.
