A simple python-based command-line utility to convert time or date stamps to epoch and back.
pyepoch is installed as a command-line utility accessible as epoch from the command-line.
You can use it to convert time or date string formats to epoch timestamps (with milliseconds):
-$ epoch '2018/1/1'
1514764800000
or if you specify, in seconds:
-$ epoch '2018/1/1' -s
1514764800
You can specify a timestamp as exact and detailed as you want it to. Additionally you can always convert back the epoch timestamp to an iso formatted date string:
-$ epoch 1514764800000
2018-01-01T00:00:00
if your epoch input is in seconds you can add a -s flag, the tool can't determine this automatically.
Feel free to report issues, this 'utility' was build out of ease as I got frustrated with manual conversion of timestamps and strings the whole time.
