Hi Jasem,

thanks for the reply

If I understand your question correctly, the DST setting can be obtained from the mount with the command (the 2010 serial meade protocol):
:GH# Get Daylight Savings Time Setting [Autostar II only]
Returns:
1# if daylight savings is enabled.
0# if daylight savings time is disabled.

After reading up on the mktime c++ function, it seems that tm_isdst can be set to -1 when dst is undefined, 0 when dst is inactive and 1 when dst is active,

Best Regards,
Martin
