| + | ===== Time Sync ===== | ||
| + | |||
| + | If your host BIOS clock is terribly wrong, you can fix the date from Internet: | ||
| + | |||
| + | * using ''rdate'', a rdate server from [[http://tf.nist.gov/tf-cgi/servers.cgi|here]]: <code> | ||
| + | [root@rescue /pld]# date | ||
| + | Sun Aug 3 03:35:46 CEST 2008 | ||
| + | [root@rescue /pld]# rdate -s time-a.nist.gov | ||
| + | [root@rescue /pld]# date | ||
| + | Fri May 15 16:03:19 CEST 2015 | ||
| + | </code> | ||
| + | * using ''ntpdate'' | ||
| + | |||
| + | **NB!**: Don't forget to sync Hardware clock: | ||
| + | <code> | ||
| + | [root@rescue /pld]# hwclock | ||
| + | Sun Aug 3 03:39:30 2008 -0.720527 seconds | ||
| + | [root@rescue /pld]# hwclock --systohc | ||
