DC_DATETIME_GMTIME(3) Library Functions Manual DC_DATETIME_GMTIME(3) NAME dc_datetime_gmtime -- convert an timestamp to GMT date and time LIBRARY libdivecomputer SYNOPSIS #include <libdivecomputer/datetime.h> dc_datetime_t * dc_datetime_gmtime(dc_datetime_t *result, dc_ticks_t ticks); DESCRIPTION Convert an integral timestamp ticks created with dc_datetime_now(3) or dc_datetime_mktime(3) into a broken-down GMT representation in result. The filled-in value consists of the year, month, day, hour, minute, and second fields. Note: unlike in struct tm, the value for year is normalised, not less 1900; moreover, the value for month is from one, not zero. The dc_datetime_gmtime function may internally invoke libc's gmtime(3), or if available, gmtime_r(3). RETURN VALUES This returns the result pointer on success. It returns NULL if ticks can- not be sanely converted or if result is NULL.
