- jstanley 4y agoWhen the timezone changes for daylight savings time, you either lose or gain 1 hour in that day (or whatever your local equivalent is).

Data aquisition instrumentation needs to use a lapsed epoch (to avoid UTC leap seconds) with a calibration at start and end of projects to adjust for drift, etc.
