I could be epoch seconds or not, you cannot tell by simply looking at a number.

Any value between 0 and $(date +%s) can be an epoch value

And numbers larger than that if the epoch value refers to some point-in-time in the future..

The standards say that the type time_t is an integral type. They don't specify whether the type is signed or unsigned. On systems with a signed 64-bit time_t, any time from the big bang to the expected collapse of the universe, could be represented as a value specifying seconds before or after the epoch.
