DATEFUDGE(1) Debian DATEFUDGE(1)NAME
datefudge - pretend the system time is different
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.
OPTIONS --static, -s
set date as a `static' one. The above mentioned system calls will always return the date passed as a parameter of the program
regardless of time passing. See EXAMPLES below.
--help, -h
print short usage information and exit.
--version, -v
print version information and exit.
EXAMPLES
Basic example:
$ datefudge "2007-04-01 10:23" date -R
Sun, 01 Apr 2007 10:23:00 +0200
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
