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
