utc timestamp question...
|
|
|
| I wrote a small function to return the UTC time stamp in the following
format:
20041130T110314
is there a better/simpler way of doing this without using CPAN modules?
#returns the timestamp in in the UTC format... in string format
#example: 20041130T110314
sub getutctime(){
my $timeval;
@{$timeval}{@{[
'sec','min','hour','mday','mon','year']}
}=gmtime(time);
#UTC returns the present year assuming 1900 is base..
@{$timeval}{'year'} +=1900;
#UTC returns 0 for Jan.. etc..
@{$timeval}{'mon'} ++;
#convert all single digit dates to 2 digits by adding "0"
while( my ($k, $v) = each %$timeval ) {
if ($k ne "year"){
if ($v<10) {
@{$timeval}{$k} = "0".$v;
}
}
}
#append all the values.. year..month.. day..hour..etc in a string
my
$timestamp=@{$timeval}{year}.@{$timeval}{mon}.@{$timeval}{mday}."T"
.@{$timeval}{hour}.@{$timeval}{min}.@{$timeval}{sec};
return $timestamp;
}

perldoc -f localtime
perldoc POSIX (search for strftime)
$ perl -MPOSIX=strftime -le'print strftime(q{%Y%m%dT%H%M%S},
localtime)'
20060119T193520
Yes, POSIX is a standard module.

Sorry, you said UTC. Replace "localtime" with "gmtime".

| Excellent thanks..
I did see the perldoc -f localtime before posting this time and had
gotten their appraoch of
use POSIX qw(strftime);
$now_string = strftime "%a %b %e %H:%M:%S %Y", localtime;
only thing i was not sure was weather i could use the "POSIX".. so i
wanted to try without it.. but yes.. ill keep my function if i am told
that i cant use POSIX.. else ill use the modual approach.. would be
much faster than mine...
Thanks for your time.

POSIX is a core module. It would be absurd for anyone to tell you it
can't be used for anything other than academic purposes.
