MM clock Greenwich Mean Time(GMT) offset and Daylight Saving Time(DST) settings. The following table lists GMT offsets and associated DST information. DST is not observed in time zones where the 'Observe DST' value does not contain 'yes' in the table. Also, note that in some cases additional information is required to determine the clock adjustment when DST is observed. The additional information is required when the GMT offset being written is +2:00 or +10:00. Examples -to set the GMT offset to +3:30, set the value to:'+3:30,no' -for Eastern Standard Time and observing DST, set the value to:'-5:00,yes' -for Egypt and observing DST, set the value to:'+2:00,yes,6' GMT Observe Additional Offset DST?
