date -d @x on old date (5.2.1)

Hello!

I want to use date but I must be able to tell it what date to process in GNU format. In kubuntu 9.04 (date 6.10) I can do:

Code:

$ date -d @1
mié dic 31 19:00:01 COT 1969

But on the old version it complains that @1 is not a valid date format. How can I use it with the old version?

Nevermind. We just saw that you can pass --date='1 week ago', for example... and that will do.

You can also compute dates relative to a specific date, not just today:

Code:

$ date -d "20090725 1 week ago"
Sat Jul 18 00:00:00 CEST 2009

The info page of the date command has a complete explanation of all the possible date formats.

Code:

info --index-search="Date input formats" date
