This template returns either 0 or 1 to indicate if [[daylight saving time]] (DST) is active in the given [[time zone]] region:
{| class="wikitable"
|-
| '''0'''
| DST is not active
|-
| '''1'''
| DST is active
|}
See below for the currently supported time zones. Note that if DST is only partially observed in a certain time zone, this template returns 1 if DST is active in that part (even though it is not observed/active in the other part).
During DST, the clock is set one hour ahead of standard time.
