git/t/helper/test-chmtime.c

/*
 * This program can either change modification time of the given
 * file(s) or just print it. The program does not change atime or
 * ctime (their values are explicitly preserved).
 *
 * The mtime can be changed to an absolute value:
 *
 *	test-tool chmtime =<seconds> file...
 *
 * Relative to the current time as returned by time(3):
 *
 *	test-tool chmtime =+<seconds> (or =-<seconds>) file...
 *
 * Or relative to the current mtime of the file:
 *
 *	test-tool chmtime <seconds> file...
 *	test-tool chmtime +<seconds> (or -<seconds>) file...
 *
 * Examples:
 *
 * To print the mtime and the file name use --verbose and set
 * the file mtime offset to 0:
 *
 *	test-tool chmtime -v +0 file
 *
 * To print only the mtime use --get:
 *
 *	test-tool chmtime --get file
 *
 * To set the mtime to current time:
 *
 *	test-tool chmtime =+0 file
 *
 * To set the file mtime offset to +1 and print the new value:
 *
 *	test-tool chmtime --get +1 file
 *
