SYNOPSIS
datefudge [-s|--static] at_date program [arguments ...]DESCRIPTION
datefudge is a small utility that pretends that the system time is different by pre-loading a small library which modifies the time(2), gettimeofday(2) and clock_gettime(2) system calls.
DATE FORMAT
The at_date argument can be given in any format accepted by the date(1) program, for example "2007-04-01 12:21" or "yesterday", or "next Friday".OPTIONS
- --static, -s
-
Mark the date as a `static' one. The above mentioned system calls will always return
the date given in the at_date argument, regardless of time passing. See EXAMPLES
below. - --help, -h
- Print short usage information and exit.
- --version, -v
- Print version information and exit.
EXAMPLES
Basic examples:
$ datefudge "2007-04-01 10:23" date -R Sun, 01 Apr 2007 10:23:00 +0200 $ datefudge "1 May 2007" date -R Tue, 01 May 2007 00:00:00 +0200 $ datefudge "2 weeks ago" date -R Wed, 16 Jan 2008 13:32:12 +0100
Non-static vs. static example:
$ datefudge "2007-04-01 10:23" sh -c "sleep 3; date -R" Sun, 01 Apr 2007 10:23:03 +0200 $ datefudge --static "2007-04-01 10:23" sh -c "sleep 3; date -R" Sun, 01 Apr 2007 10:23:00 +0200
