What it means
Where is that on the timeline?
All dates are UTC. Unix time and these counts ignore leap seconds; Excel serials follow the 1900 date system and start at 1 March 1900.
The math
How to convert ms to s
date = 1970-01-01 00:00:00 UTC + timestamp seconds. Excel serial = Unix ÷ 86,400 + 25,569; Julian Date = Unix ÷ 86,400 + 2,440,587.5.
Example: 1234567890 ms = 1234568 s.
