Hi,

Firmware 1.1.1.14 for the GXP2000 supports automatic Dalight Savings 
Time adjustment (AFAIK it was introduced in 1.1.1.11).
Upgrade the firmware and add the following to your .cfg file or set via 
the webpage...

# Daylight Savings Time: 0 - No, 1 - Yes
P75 = 1

# Daylight Savings Time optional rule
P246 = 04,01,7,02,00;10,-1,7,02,00;60

This rule is for Eastern Standard Time in the US and Canada, for other 
locations, see the Release Notes for the HT386, 488 and 496 at
http://www.grandstream.com/DOWNLOAD/FIRMWARE/HT386_488_496/Release_Note_HT386-488-496_1_0_3_44.pdf
for details of the Optional Rule

regards,

Drew
