Epoch Start
Unix time starts at 1970-01-01 00:00:00 UTC.
Seconds vs Milliseconds
A 10-digit timestamp usually means seconds. A 13-digit timestamp usually means milliseconds.
Timezone Handling
The timestamp identifies one instant. Local and UTC displays are different views of that same instant.

Unix Timestamp FAQ
What is a Unix timestamp?
A Unix timestamp is the number of seconds since 00:00:00 UTC on January 1, 1970.
Is Unix time based on my local timezone?
No. Unix time is counted from a UTC reference point. Local timezone only affects the calendar display.
Should I use seconds or milliseconds?
Use seconds when an API asks for epoch seconds, and milliseconds when JavaScript or logs expect epoch milliseconds.
