$ ri utime
------------------------------------------------------------ File::utime
     File.utime( anAccessTime, aModTime [, fileName]+> ) -> aFixnum
------------------------------------------------------------------------
     Changes the access and modification times on a number of files. The
     times must be instances of class Time or integers representing the
     number of seconds since epoch. Returns the number of files
     processed. Not available on all platforms.
        File.utime(0, 0, "testfile")          #=> 1
        File.mtime("testfile")                #=> Wed Dec 31 18:00:00 CST

        File.utime(0, Time.now, "testfile")   #=> 1
        File.mtime("testfile")                #=> Sun Mar 04 23:28:25 CST
