I'm pretty sure the machine's hardware clock (RTC) has the wrong date. At
boot time the operating system time is initialized with that time.

I don't know tru64, but settimeofday must not necessarily set the machine's
RTC. For example under linux there's a special command which writes the
time of the software clock to the RTC. Sometimes this is called
periodically every few minutes, and im most cases it is run when the system
shuts down.

You must check which command tru64 provides to do so.
