Today I looked at a system that has weird timestamp/clock issues?
Anybody seen this before, know what it is?
I have some excerpts of commands below that demonstrate the issue.
Please note the 2006, and April 15 dates on some of the processes and
file timestamps as well as process times last year, when the "uptime"
says only 17 days (March 25th).... But I could swear that the box has
been up for a LONG time (like maybe 2+ years?)
Doesn't make sense.
This is our billing server, so if the system clock/date is skewing
wildly this could cause havoc with our accounting.
