integer
Returns an integer representing the time zone
that is currently set on the device.
The returned integer represents the number of
minutes the time zone is offset from Greenwich
Mean Time (GMT), as established in Greenwich,
England. For example, if the time zone is offset
from GMT by two hours, the device would return
120 (minutes).
Integers for time zones west of GMT are negative.
Integers for time zones east of GMT are positive.
If Greenwich Mean Time is 14:07:07, it is:
8:07:07 a.m. in Denver, Colorado (Mountain
Daylight Time) (–360 minutes from GMT)
16:07:07 p.m. in Brussels, Belgium (Central
European Standard Time)
(+120 minutes from GMT)

category (such as Length) and its default unit
(such as _m for meters).
To set the default units, use
