While looking for a 'find' substitute I stumbled across a program
on my disk called 'warp' to execute a command in a different time
frame. It was written by Glenn Fowler and I think it's a cool ksh
script; you can not only shift but also stretch the time scale.
Just want to share... - I put a copy at volatile.gridbug.de/warp
Man page can be retrieved by: warp --man

DESCRIPTION
warp executes a dynamically linked command in a different time frame by
intercepting time related system calls and modifying the times seen by
command using the formula:
time = time + warp + (time - base) * (factor - 1)
...

(Note that it needs commands to be dynamically linked to work.)

Enjoy.

I guess it was popular at the time when propietary software came
with licenses that only lasted for a month or a year. I remember
myself in the 90s changing the system time clock in order to make
some program work.

Yes. But it has also several [legal] application usages. - I recall
to have used it in a testing context where the time frame mattered,
and in context where I had to slow down or speed up the time scale.
(But don't recall the details, that was way back.)

Which provides the "faketime" command, installable on Ubuntu and
probably other systems:

$ faketime 'jan 1 1970' /bin/date
