I believe your setting TZ=MST provides insufficient information for the localtime function to determine the correct time zone offset. My understanding is that the TZ setting must include the hours offset from UTC, and that the alphabetic designation you give it is merely for human convenience. So in your case, it would be TZ=MST7 or, perhaps, TZ=MST7MDT to account for the switch to daylight savings time.

Update: sporty's right -- I determined this only for Windows. My Linux box did just fine without the numeric offset. (Thanks for the info on /usr/share/zoneinfo.)

    It depends on the system. I'm gonna guess you are talking about windows only, but in case you aren't..

    It's because of what's in my /usr/share/zoneinfo/ dir .. so if I created a new one, I could use that, without the number.
