Is there ever a good reason to store time not in UTC?

Question

I am wondering if there are any good reasons to ever store time information in anything other that UTC (GMT)? I believe that this is a solid rule for all software engineering. T

Answer 1

UTC is a time-keeping standard that has the accuracy and precision of TAI, but with leap seconds added in at irregular intervals to allow it to closely track mean solar time (UT1).

If the system that you are working with cannot handle leap seconds, then the Bureau International des Poids et Mesures recommends that TAI be used instead of UTC.
