Thanks a lot to:

Robert Schuhl
Paul Watson
For their quick answers.
The origital question was:
When shutting down our system and verifying the date at the console prompt
(>>> date), the time is correct but the year is always 2047. Wenn changing
the date at HW level to the correct one, I get a warning when rebooting that
the system has not been booted since 5 years, and that the date should be
checked and reseted. Verifying the date at the Tru64 prompt shows that the
date and time are correct. Shuting down gives the wrong date again. This
appends on the 2 systems I manage. I have console rev 5.3.
And I got 2 kinds of answers:
Paul Watson suggested that the small button battery on the motherboard which
powers the system clock needs replacing.
Peter Braack posted the following extract of some Digital sources:
The TOY (also called real-time clock or BB_WATCH) is located on the
motherboard at location (E78) 21-32423-01.
Note: For Alpha systems the TOY or real-time clock is now called the
BB_WATCH. Although VMS and UNIX systems use the BB_WATCH (or TOY) to read
the correct date and time during a boot, it should not be set from the SRM
console level. The time should only be set by the operating system. Ignore
the SRM date and time setting that is displayed from the console (>>>DATE),
this is WRONG at best. The [SRM Console] DATE function is now supplied only
as a tool for manufacturing to time stamp extended periods of run time. In
the past engineering has tried to do date conversions but found that to be
an impossible task. Each operating system has its own format, and in some
Alpha's, the date format is platform specific.
And this is my personnal comment:
As soon as the TOY clock time is being incremented when the power is
switched off, then a battery problem should be excluded. So 2047 must a date
for some special compaq event like Alpha phase down...
