|dealing with summer time|
romance standard time +2
| 8:08 am on Mar 18, 2006 (gmt 0)|
i've got a function which checks that there are minimum 3 days between 2 dates.
currently i convert to milliseconds and subtract one from the other and check that it is < 24*3600*1000*3
but this is giving me problems if i check dates around the 27th march - which is when summer time starts - i lose an hour and the function returns negative even there are 3 days in between.
is there a way around this particular problem?

Yes, you should avoid calculating days using milliseconds because of daylight savings time. This should give you the idea.
return new Date(this.setDate(this.getDate()+days))
alert('-20 = '+new Date().moveDays(-20)+'\n\n+20 = '+new Date().moveDays(20))

that's what i've now done. i didn't actually understand what you meant, until i did some investigating and now it's clear.
