I want to measure the time of start for a program but for this I want to get the timestamp in Windows, but I need to get the time-stamp in mili-seconds since the Unix epoch format. (The Unix epoch is the time 00:00:00 UTC
on 1 January 1970
(or 1970-01-01T00:00:00Z
ISO 8601
).)
How can I get timestamp in milseconds since Unix epoch through a Windows command?
