 ap> It might not work with daylight savings, it also might not work in
 ap> UTC-?? timezones.

from the sources:
snprintf(buffer, 256, "TZUTC: %02d%02d", offhour, offmin);

this will return somthing like -700 for negative timezones. I think this should
 work better:

snprintf(buffer, 256, "TZUTC: %0*d%02d", (offhour < 0) ? 3 : 2, offhour,
offmin);
