DST Testing

vpons — Wed, 07 Mar 2007 12:21:09 GMT

I read a couple of threads and all suggest that use perl to test new tztab file for DST setting.

Can you please suggest anyother method to test if the DST changes have taken into effect?

I will be deploying the tztab file that I extracted from the patch tonight.

Of course there is. Make your tztab changes either manually or preferably with a patch and then set your system date ahead to about 2 hours before the expected transition. Wait for the transition and then set the date ahead to about 2 hours before the next transtion and see if all was as expected. Next, use the date command to set the time backwards to the correct time.

Your final step should be to hit yourself over the head with a baseball bat because almost certainly you have clobbered database timestamps and file timestamps so don't complain if your data are inconsistant or your makefiles no longer work.

Sure clay! I am aware of the mess the time change will create and I do not want to try on the only server(production) that I have.

My system does not recognize your script.
I get the following output with
perl -v

This is perl, v5.6.0 built for PA-RISC1.0

And I have perl under
./usr/bin/perl
./usr/contrib/bin/perl
./usr/perl5/bin/perl

I tried running your script under all the three but it does does not work

# dst.pl -y 2006
sh: dst.pl: not found.
[root@sloss58]/usr/perl5/bin

TZ=CST6CDT dst.pl -y 2006
sh: dst.pl: not found.
[root@sloss58]/usr/perl5/bin

Any suggestion?

Your problems have nothing to do with Perl and everything to do with the shell. You are simply being told that dst.pl is not found anywhere in your current PATH. It's also possible that you haven't set the executable bit on the file. In any event, your problems aren't covered in Perl 101 but rather in Shell 101.

Because your perl -v works and points to perl 5.6, you should have no trouble.

cd to whatever directory you downloaded dst.pl to.

chmod 755 dst.pl

./dst.pl

and you should be fine.

Hi:

# ./dst.pl -y 2006

...would work better as root unless you have "." in root's PATH (which I hope you do not!).

You can never go wrong using an absolute path name for execution, either.

Oh, your problems are much more fundamental than PATH problems. I am not trying to insult you but if you are having problems as trivial as this, you should not have root access and should not be allowed to patch anything. "Fixing" DST may be the least of your systems problems. Someone has put you in the pilots seat and asked you to fly without sending you to flight school first.
