JS: Check if date is less than 1 hour ago?

Question

Is there a way to check if a date is less than 1 hour ago?

Something like this:

Answer 1

Define

var ONE_HOUR = 60 * 60 * 1000; /* ms */

then you can do

((new Date) - myDate) < ONE_HOUR

To get one hour from a date, try

new Date(myDate.getTime() + ONE_HOUR)
