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

Fri Feb 13 23:31:30 UTC 2009

date -d 'now' +%s

date -d 'now +10hours' +%s

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

In my opinion, org mode is too rigid in respect to timestamp format. 
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 
windows year 1900 has Feb, 29...
