in reply to Epoch time conversion in CSV

      I am generating a CSV file with the first 2 columns in the Epoch time format.

Here is some sample code:

#!/usr/bin/perl -w use strict; use Data::Dumper; my $line=<DATA>; chomp $line; my @f=split(',',$line); my $dt1=shift @f; my $dt2=shift @f; printf "%s,%s,%s\n",scalar localtime($dt1),scalar localtime($dt2),join +(",",@f); exit(0); __END__ 1345752662, 1345752673, CLOSED, CRITICAL, Other fields etc
The working part of this really is the scalar localtime part. There are other ways of doing this, but this is a time honored method that works. Brute force, but it works.

Here is what perldoc -f localtime says that is pertinate to your situation:

If EXPR is omitted, "localtime()" uses the current time + (as returned by time(3)). In scalar context, "localtime()" returns the ctime(3) v +alue: $now_string = localtime; # e.g., "Thu Oct 13 04:54 +:34 1994" This scalar value is not locale-dependent but is a Perl builtin. For GMT instead of local time use the "gmtime" builtin.
Hope this is of some help.

[Discipulus]: Ah! if so you must play with him not with us ;=)
[vrk]: Hope he gets better soon.
[Discipulus]: hdb sorry i profit; is known that a prime number is never a figurate one nor the sumattion of two adjacent figurates of the same order? like 3th triangular+3th tetrahedric
[Discipulus]: if known where i can read about the matter?
[choroba]: he's not really sick, we just got nobody to look after him today
[Discipulus]: create an account for him; we are funny baby sitters ;=) come here child, want to listen the typeglob tale?
[vrk]: choroba Oh, that's good.
[vrk]: Discipulus I don't know much about prime numbers, but wouldn't that kind of an answer be in a graduate-level number theory book?
[Discipulus]: my 8 yo daughter has two weeks of sleep disturbs.. we are gonna be crazy..
