Top Forums Shell Programming and Scripting Set system date to some date (Sunos) Post 302378401 by jim mcnamara on Monday 7th of December 2009 09:16:48 PM

IF you set the system date using the date command ( assuming you are not running ntpd or xtnpd) then that will change the system time.

Anything else is just sort of silly. You can use TZ to mess around with a few days, as you have discovered, but it is NOT changing the system date: that is set as the number of seconds since Jan 1 1970. To truly change the date you have to reset system time with the date command - which is NOT a great idea. crontab can get confused, for example.

What are you really trying to accomplish - answer does not include not playing with TZ?
