Problem: Language and Time Settings->Time Zone drop menu

The time zone drop menu in the Server Manager->Language and Time Settings lists the times all off by 1 hour.

i.e. Pacific time is not GMT -7:00 it is supposed to be -800, Alaska is not -8:00 it is supposed to be -9:00 etc, the entire list is shifted by 1 hour.

This is likely a Java / OS issue. You can specify the proper timezone during startup, see also

Spark Timezone Settings.

If you are using a daylight saving time currently then the additional GMT offset is likely +1 hour, this is displayed properly by the JVM while Windows does ignore this fact.

Ah right daylight saving time will change GMT. Thanks.
