datetime.SystemTimeZone
datetime: tz = datetime.SystemTimeZone ()
System time zone setting.
tz = datetime.SystemTimeZone () returns the time zone of the
system where Octave is running, as the name of a zone in the IANA Time
Zone Database, such as 'Europe/Athens'. It is 'UTC' when
the system time zone cannot be determined. The parentheses may be
omitted, and the same value is read from any datetime array d as
d.SystemTimeZone.
