Javascript,getTime()

I am trying to understand something about getTime(), My problem is that, I am setting up a new Date with lets say: 23,07,2012. When I am using getTime() on it I should get the milliseconds Since 01,01,1970. When I divide the value I getting from getTime() with (1000*60*60*24) I should get the days number was pass since 01,01,1970 until 05,07,2012 but somehow I get a number with a Decimal point (15543.875) I dont understand why, I mean since 01,01,1970 and 23,07,2012 I should get an integer(that what I think), well I know I am really wrong, if can someone please help me understand why the decimal point at the result.

If you are setting a date like new Date(2012, 06, 23) It will be set according to the timezone of the client, where as .getTime() is UTC. You want Date.UTC:

Date.UTC(2012,6,23) / (1000*60*60*24)
//15544 For any computer

new Date(2012, 06, 23) / (1000*60*60*24)
//15543.875 For my computer, I am coincidentally in  the same timezone as Israel. This result will depend on what timezone the client is.
