NAME

4     dc_datetime_gmtime — convert an timestamp to GMT date and time
5

LIBRARY

7     library “libdivecomputer”
8

SYNOPSIS

10     #include <libdivecomputer/datetime.h>
11
12     dc_datetime_t *
13     dc_datetime_gmtime(dc_datetime_t *result, dc_ticks_t ticks);
14

DESCRIPTION

16     Convert an integral timestamp ticks created with dc_datetime_now(3) or
17     dc_datetime_mktime(3) into a broken-down GMT representation in result.
18     The filled-in value consists of the year, month, day, hour, minute, and
19     second fields.
20
21     Note: unlike in struct tm, the value for year is normalised, not less
22     1900; moreover, the value for month is from one, not zero.
23
24     The dc_datetime_gmtime function may internally invoke libc's gmtime(3),
25     or if available, gmtime_r(3).
26

RETURN VALUES

28     This returns the result pointer on success.  It returns NULL if ticks
29     cannot be sanely converted or if result is NULL.
