give Date a number, it's standard time. don't give date a number? daylight savings time.

I’m going to guess it’s because Wednesday, Dec 31 1969 (which is Jan. 1 1970 + 1000 milliseconds, adjusted for your time zone) was not during Daylight Savings Time, whereas Sat Aug 13 is. Since Daylight Savings Time does not apply to UTC, the timezone offset changes for dates that are in DST for your locale.

@SlaunchaMan Ooh, good catch. I think the real issue that I'm having with this is that there's no explicit way to set the UTC offset of a new Date object.

I can see how that would be a problem. :)

@tbranyen so, given '1313212826216 -0600', how do you convert that into UTC?

this might be what I'm going for -- show the originating "local" time for a timestamp, along with the UTC offset.

(e.g., given 1310976115000 -0700 and I am UTC-0500 (CDT), I want to see 'Mon Jul 18 01:01:55 2011 -0700', not 'Mon Jul 18 2011 03:01:55 GMT-0500 (CDT)'
