from
Returns an Instant that is epochMilliseconds number of milliseconds from the epoch instant 1970-01-01T00:00:00Z.
The return value is clamped to the platform-specific boundaries for Instant if the result exceeds them. In any case, it is guaranteed that instants between DISTANT_PAST and DISTANT_FUTURE can be represented.
Note that Instant also supports nanosecond precision via fromEpochSeconds.
