问题 I was reading basics of Perl programming language and I came across the following statement Perl is Y2K compliant. Did not quite get what it meant even after some Googling.

Then I'd use datetime.datetime.replace on the object if it is past your ceiling date -- Adjusting it back 100 yrs.: import datetime dd = datetime.datetime.strptime(date,'%y%m%d') if dd.year > 2005: dd = dd.replace(year=dd
