See this post for the info you are looking for.

Thanx RTM !!!

Isn't there any OS built system utility e.g. something like "sysdate"

Also I chked the post u suggested.
Another query --- When I type

# date
Wed Nov 13 13:54:09 CST 2002
#d=`TZ=a30 date +%a' '%b' '%e' '%T' '%Z' '%Y`
#echo $d
Tue Nov 12 13:54:38 a 2002

Now, Can you pls. help me how to display the Time Zone properly.

Regds,

There is not a sysdate in UNIX.

As far as your command, why are you setting the TZ and where are you getting the information? This is the portion that is incorrect.

(fyi - you don't need all those quotes)
$ d=`date +'%a %b %e %T %Z %Y'`
$ echo $d
Wed Nov 13 15:55:37 EST 2002

What Unix are you using?
There may be a different answer if you're on Linux or if you have GNU Date installed...

I did it another way. Put a cron to run at 2315 daily to create a file with yesterday's date in whatever format u need. ANd read the file when u want. It is not the most elegant solution but it works for me!!

I'm using SunOS 5.7
RTM - Thanx for the " quotes thing " but after setting TZ=a30, I get yesterday's date. Similarly I dont just want yesterday's date..it can be any number of days back.

Just for additional knowledge, if u can help me out with the timezone error then it would be great.

Anyways, i got a script which converts the date to any number of days back.



Thanx all for ur replies.
