Just a word of caution: dealing with dates and times is much trickier then it might look at first sight.

Think for example that even for common situations, the 'distance' between yesterday and today might be anything between 1 second (yesterday 23:59:50 and today 00:00:00) and 48h - 1 second (yesterday 00:00:00 and today 23:59:59).

If it happens that it is 'one of those days' when daylight saving times changes, the day might have 25h or only 23h... And so on.

You might want to have a look on the documentation of Date::Manip to get some oversight; don't be scared, you'll soon find a reliable friend in it, but just realize that depending on the accuracy you need you might want somewhat different approaches.
