You can do as,

date [mmddhhmm[[cc]yy]]
date 1231000037

It will work.

Yes. There is a problem in time_s or time_x structure in all unix systems. I heard that it is a problem of y2037 problem or something. ?!

Anyway try to do as,

date 0101000038

Is it working?

Hi Varian,

Actually this is a known UNIX bug & it has to do with how the date is tracked. It uses seconds past midnight Jan 1 1970.
It can only hold 2 to the 31 power which is Jan 19 2038.
This can usually be solved by using a 64-bit system, but you already are running one so I suspect you probably need a patch or firmware update.
I searched the patch database & could find no explicit patch for this so you should probably log a SW call with the Response Center.
See this URL for a little perl script to see if the system is 2038 compliant.

HTH,

You don't and can't set the date past Dec 31st, 2037 at this time!

11.23 is 64bit, but some commands are not yet.

getdate will work, providing you use the correct options.

man getdate
man ctime

You cannot use date command, it is 32-bit build. Instead you might have to write your own program using *date* APIs. You have to go through the manpages to see what will work and what will not.

To start with do 'man date' and look for other date related routines in "SEE ALSO" section.

Actually there is NO patch, as this isn't deemed an issue as of yet:

man date

on an Itanium (11.23 with the absolute most latest patches):

Currently, the maximum date supported is December 31, 2037 23:59:00 UTC.
