So, you want to take the string "2011-03-02T15:30:00+01:00" and create a
SysTime from it? Well, that's the extended ISO format, so just use
SysTime.fromISOExtString. e.g.

auto st = SysTime.fromISOExtString("2011-03-02T15:30:00+01:00");

You'll get a SysTime with the appropriate value for stdTime (in UTC), and
it'll have a SimpleTimeZone with a UTC offset of +1 hours. And if you want
that to then be in a different time zone, you can then convert it to other
time zones via toUTC, toLocalTime, or toOtherTZ (or by just setting its time
zone if you want to mutate it rather than getting a new value).
