2 * This program can either change modification time of the given
3 * file(s) or just print it. The program does not change atime or
4 * ctime (their values are explicitly preserved).
6 * The mtime can be changed to an absolute value:
8 * test-tool chmtime =<seconds> file...
10 * Relative to the current time as returned by time(3):
12 * test-tool chmtime =+<seconds> (or =-<seconds>) file...
14 * Or relative to the current mtime of the file:
16 * test-tool chmtime <seconds> file...
17 * test-tool chmtime +<seconds> (or -<seconds>) file...
21 * To just print the mtime use --verbose and set the file mtime offset to 0:
23 * test-tool chmtime -v +0 file
25 * To set the mtime to current time:
27 * test-tool chmtime =+0 file
