I have used this code in a Chrome extension. See https://github.com/aykevl93/Chrome-Sync.

The code is assuming that if it’s a string, it’s already human-formatted and needs to be parsed. So if the date is “Sun Apr 10 2011″, then “new Date(‘Sun Apr 10 2011′)” will parse the string and create the correct date.

I assume that you have the situation where you have a string representing the number of milliseconds since 1970, such as “1302418800000″. In that case, you definitely would have to parse the int.

Thanks!

One correction: when the olderDate is a string, this is needed (see the parseInt):
if (typeof olderDate == “string”) olderDate = new Date(parseInt(olderDate));
otherwise it won’t work (or am I supposed to do something different?)
