You can use the date command. Here is the cut and paste from the man for date:
date [-u] [mmddhhmm[[cc]yy]]

Set the HP-UX system clock to the date and time
specified. You require the superuser privilege
If you include the -u option, the specified date and time
is assumed to be in Coordinated Universal Time (UTC).

The numeric argument is interpreted left to right in
two-digit pairs as follows:

mm Month number [01-12].
dd Day number in the month [01-31].
hh Hour number (24-hour system) [00-23].
mm Minute number [00-59].
cc Century minus one [19-20].
yy Last two digits of the year number
If omitted, the current year is used.

If you attempt to set the date backwards, date generates
the warning,

do you really want to run time backwards?[yes/no]

Type yes or the equivalent for your locale to set the
clock backwards; anything else to cancel the command.

Here is an example of the command:
date -u 011610222004
This sets the date/time to 01/16/2004 10:22 AM
