[Freeswitch-users] How to get GMT date/time in channel variable "start_stamp", instead of local

Hi, Right now channel variable "start_stamp" represents *local *date/time (to remind, it contains value in following format: 2010-05-01 16:31:58) Is there a similar variable (like start_stamp_gmt?) that will provide *GMT*formatted date/time? Or maybe there are some settings that will make FreeSWITCH provide all date / time formatted variables in GMT instead of local. Thank you, Vitalie
