(Perl) Compute Difference Between Two DateTime StringsDemonstrates how to compute the difference between two datetime strings.
use chilkat(); # Imagine we have these strings: $t1 = "2022-11-14 15:45:38"; $t2 = "2022-11-16 17:23:41"; # How many minutes are between the two? # First, we'd want load each date/time into a Chilkat CkDateTime object. # In this case, there are no CkDateTime methods that accept the above format. # However.. the CkDateTime's SetFromTimestamp will accept a date in the format "YYYY-MM-DDThh:mm:ssZ" # First modify the above dates to the timestamp format. $sb1 = chilkat::CkStringBuilder->new(); $sb1->Append($t1); $count = $sb1->Replace(" ","T"); $sb1->Append("Z"); $sb2 = chilkat::CkStringBuilder->new(); $sb2->Append($t2); $count = $sb2->Replace(" ","T"); $sb2->Append("Z"); # Load each into a CkDateTime $dt1 = chilkat::CkDateTime->new(); $dt1->SetFromTimestamp($sb1->getAsString()); # verify... print $dt1->getAsTimestamp(0) . "\r\n"; $dt2 = chilkat::CkDateTime->new(); $dt2->SetFromTimestamp($sb2->getAsString()); # verify... print $dt2->getAsTimestamp(0) . "\r\n"; # Get the difference in seconds $diffSeconds = $dt2->DiffSeconds($dt1); print "Difference in seconds: " . $diffSeconds . "\r\n"; print "Difference in minutes: " . ($diffSeconds / 60) . "\r\n"; |
