source: MondoRescue/branches/stable/mondo/mondo/mondoarchive/main.c@ 810

Last change on this file since 810 was 810, checked in by andree, 18 years ago

Fix new time stamp log feature:

  • use ctime() which gives human-readable time output rather than get_time() which gives seconds since epoch (also fixes segmentation fault caused by get_date() returning long and out being %s);
  • unlink the log _before_ start time is written to it so we don't lose it
  • call it 'time' rather than 'date' plus some cosmetics
  • Property svn:keywords set to Id
