DateTime duration in seconds
It has been too many times that I forget how to get a DateTime::Duration
between two DateTime objects in seconds (and nanoseconds). That is, where I
can then do ->seconds and have the duration in seconds between the two dates.
I know it’s in the DateTime POD, but I keep forgetting it, and it takes me
always a lot of time to find it back.
Here it is so that hopefully the next time I search for “Perl DateTime Duration seconds” on the Intarweb, it shows up…
my $duration = $dt2->subtract_datetime_absolute($dt1);
my $seconds = $duration->seconds();
