how to get an earlier date hp ux

[idi]

hi,
i need to get an earlier date, but do not know how to do.Is there any command for this?

Are you asking for HP-ux 9.04, 10.20, 11.00 ??

Are you asking to set the date of the system back to an earlier date?

Setting the system date back in time can be dangerous, especially if you have time sensitive applications like databases.

I could not quite clearly understand your question but it must be one of these two scenarios.

1. you want to change the date of a file to previous date (not very wise if the file is being used by an application dependent on the modification date and time but it can be done). If this is the case, use the "touch" command as follows

touch -t YYMMDDhhmm filename

2. you want to know what day of the week certan number of days ago, or what was the date lets say 129 days ago etc. In which case please use the script of your choice (PERL or Shell) provided by Clay Stephenson of these forums, found here:

PERL Version: http://mirrors.develooper.com/hpux/caljd-2.2.pl

HI,
it's the same date command that you have to use.
See the man pages for format

If you want to adjust the system date, the format is:

date MMDDhhmmCCYY
where MM=two digit MONTH
DD=two digit DAY
hh=two digit MILITARY time (1pm = 13)
mm=two digit minute
CC=two digit CENTURY (20 or possibly 19)
YY=two digit YEAR

So to set the date back to February 28th, 2005 at 1:18 PM, do this:

date 022813182005

But again, I stress that this can be dangerous! Going back past Y2K (2000) can also cause issues. A reboot might me necessary in either case.

Hi,
There are two conditions
1. If you want to adjust or change the system date, the format is:

date MMDDhhmmCCYY
where MM=two digit MONTH
DD=two digit DAY
hh=two digit MILITARY time (1pm = 13)
mm=two digit minute
CC=two digit CENTURY (20 or possibly 19)
YY=two digit YEAR

2. If you want to know the previous year or month ...then the command is "cal"

# cal 7 1999

this will show you the monthly view of July 1999.

syntax is : # cal

I think this should solve your purpose...

[Muthukumar_5]

you can use cal command for this also.

cal to view previous date with day informations.

hth.

[idi]

i mean, how i know 15 day before today,
for ex:

today system date is: Fri Jan 8 08:34:34 EETDST 2005

and when i give '15 day defore' for input,
i want to see

Dec 24 2004 for an output.

So How?

Hi,

You can write a little programme in C with time function.

See man page with the command "man 2 time".

Use the attached script, caljd.sh.

Then it's very easy:

DT=$(caljd.sh $(caljd.sh -p 15))
echo "Date 15 days ago was ${DT}"

Invoke as caljd.sh -u for full usage and many examples.
