Clock

Select Local or UTC (Coordinated Universal Time) by using the down arrow on the entry field.

Local
Sets the Time to the current time of the time zone that you selected.
UTC
Sets the Time to the Greenwich Mean Time (GMT) no matter what time zone you have chosen.

Note: You should not specify Local when the Time zone specifies not initialized. That combination does not guarantee that the actual time zone that is being used is what you really want.
