Hi All,

I have this strange scenario.

Code:

[root@server 1]# perl -MTime::ParseDate -e 'printf "%s\n", &parsedate("2012-10-25 10:28:41")'

This gives the answer as : 1351178921

Code:

[root@server 1]# perl -MTime::Format -e 'printf "%s\n", $time{'yyyymmdd_hhmmss',1351178921}'

This Gives the asnwer as : 20121025_102841 ( This is correct as expected )

But when i run the same code in another server it gives out different result for Time::Format

Code:

[root@server 2]# perl -MTime::Format -e 'printf "%s\n", $time{'yyyymmdd_hhmmss',1351178921}'

This Gives the asnwer as : 20121025_102817 ( Wrong answer)

I dont understand why we have a difference of ~24 sec between the result created in these two server ....they are using the same version of perl module and all configuration are similar.

The only differnce i notice that the System Time between both server varies by ~24 seconds.So my question is dose Time::Format consider the SYSTEM TIME for conversion....are they related ?

Sserver 1 : Result for date Command
Tue Nov 6 01:18:15 EST 2012

Server 2 : Result for date Command
Tue Nov 6 01:17:51 EST 2012

Any suggestion on what causing this issue ?

Regards
Ashesh

I'd ask the developer Eric J. Roode, you'll find his contact details on the Time::Format page on CPAN

You could just look through the code and see what's what ...

~24 seconds being the difference in server time and the difference in output, looks a bit convincing for use of the system time all the same

Thanks for the info,
But i have tried this code in two different server ( with a time differnce of 25+ sec) but both gives the same outout for Time::Format piece of code.

So i believe the ~24sec gap between the server may not be the real reason for above said issue ....

My impression is that it would not make any sense for the module to use the current system date to achieve conversion of dates passed to it. The 24 second difference between the two server could shed some doubt on this impression, but I still can't believe it.

Having said that, I have no idea as to why it should give different results on different servers, especially if it is the same version of the module.

I'll give a try on the various servers on which I have access.
