Setting the date on a Sun Fire x4100 M2 is pretty straight forward. To set the date, perform the following steps:
1. Log into the ILOM via ssh
2. set /SP/clock/ datetime=052509262011
where 05 = mm
25 = dd
09 = hh
26 = mm
2011 = yyyy
3. After entering in the new date and time, you can confirm it by typing show /SP/clock
