None the less, for the Empeg to automate DST requires more detailed location info and an appropriate database of DST rules.

To cover the world wide case this includes places that have non-integer hour time offsets, such as Australia, India, Iran and Nepal (UTC +5:45!!!).

Still, using GPS to set the minutes to an accuracy of better than a second is possible even with serial port delays. GPS can totally eliminate clock drift.
