You do not need a steam hammer. There are a number of tools around. Some 
of hammers however could not deal with all nails.

Even "date" util could be used to convert between timestamps and human

TZ=America/New_York date -d "@`TZ=Europe/Berlin date -d '2020-11-10 
09:08:07 +10hours' '+%s'`"

Sometimes I would prefer to specify timestamps with timezone.

Timestamps in xls files are represented by floating point numbers, 
namely days since 1 Jan 1900, fractional part is time. Unfortunately 
1900 is not a leap year, so to avoid unnecessary complications of code 
and keep memory footprint small, on Macs epoch starts in 1904, on
