13 toUTCTime(size, d, res)
19 struct tm *tm,*tmp=(struct tm *)res;
28 t = - (time_t) ((StgInt *)d)[0];
33 t = (time_t) ((StgInt *)d)[0];
44 gmtime() may return a ptr to statically allocated storage,
45 so to make toUTCTime reentrant, we manually copy
46 the structure into the (struct tm *) passed in.
48 tmp->tm_sec = tm->tm_sec;
49 tmp->tm_min = tm->tm_min;
50 tmp->tm_hour = tm->tm_hour;
51 tmp->tm_mday = tm->tm_mday;
52 tmp->tm_mon = tm->tm_mon;
53 tmp->tm_year = tm->tm_year;
54 tmp->tm_wday = tm->tm_wday;
55 tmp->tm_yday = tm->tm_yday;
56 tmp->tm_isdst = tm->tm_isdst;
58 If you don't have tm_zone in (struct tm), but
59 you get at it via the shared tmzone[], you'll
60 lose. Same goes for the tm_gmtoff field.
64 strcpy(tmp->tm_zone,tm->tm_zone);
65 tmp->tm_gmtoff = tm->tm_gmtoff;
