swami has asked for the wisdom of the Perl Monks concerning the following question:

Hi, I was trying to calculate the time difference b/w two input timestamp in perl. But i am not getting the value. Should i do any formatting of input paramters.
#!/usr/bin/perl use POSIX; my $ts1 = "$ARGV[0]"; my $ts2 = "$ARGV[1]"; $diff = ($ts1 - $ts2); print int($diff);

    Hello swami, welcome to the Monastery.

    Please, wrap your code sample into <code> ... </code> tags. See Markup in the Monastery.

    What is the expected format of the input? Plese, show example input and expected output.

    Hi,

    "... I was trying to calculate the time difference b/w two input timestamp in perl..."
    Please, I don't see how you are doing that here.
    However, in the first place, you might want to properly placed your script in code tags see How do I post a question effectively?
    Then, in the code you posted, I believe you intented $ARGV[1] NOT $ARGV1

    If you tell me, I'll forget.
    If you show me, I'll remember.
    if you involve me, I'll understand.

    G'day swami,

    Welcome to the monastery.

    You'll need to show us your input as well as the actual and expected output. Guidelines for this are given in: How do I post a question effectively?

    There are lots of date-related modules on CPAN; for instance, Date::Calc might be appropriate for your needs.
