Date calculation

[Guest_imported]

OK, this is a bit complicated scenario. I am currently designing a forum and I want to calculate the posts per day for a user. I have only got the users date of registration (Format: DD,MM,YYYY,HH,MM,SS) and the post count. To calculate the posts per day, I have to find out the days from the registration to the current date (only the days not the exact time). How is that possible?

Use the Date object's

.valueOf()

function which returns the milliseconds elapsed since the base date.

(today.valueOf()-registered.valueOf())/(1000*60*60*24)

Once you have the millisecond difference between dates, convert it to days. Then you can

Math.round()

it if you want.

Great, there's only one problem. In the forum the registration date is stored in a string with the format "DD.MM.YYYY HH:MM". So I have to convert it to a "valid" date to use the valueOf function right? So how do I do that?
