customEpoch

Optional. Enter a value here to use a custom epoch, instead of the standard epoch (which started at 1970-01-01T00:00:00 UTC). Specify the start time of the custom epoch, in YYYY-MM-DDTHH:MM:SS in UTC. The time must be 2000-01-01T00:00:00 or later. Always set the MM:SS portion to 00:00.
