Converts time_ into an RFC 3339 encoded string, relative to the
Coordinated Universal Time (UTC). This is one of the many formats
allowed by ISO 8601.
ISO 8601 allows a large number of date/time formats, with or without
punctuation and optional elements. The format returned by this function
is a complete date and time, with optional punctuation included, the
UTC time zone represented as "Z", and the tv_usec part included if
and only if it is nonzero, i.e. either
"YYYY-MM-DDTHH:MM:SSZ" or "YYYY-MM-DDTHH:MM:SS.fffffZ".
This corresponds to the Internet date/time format defined by
RFC 3339,
and to either of the two most-precise formats defined by
the W3C Note
Date and Time Formats.
Both of these documents are profiles of ISO 8601.
Use Date.timeFormat or g_strdup_printf() if a different
variation of ISO 8601 format is required.
If time_ represents a date which is too large to fit into a struct tm,
NULL will be returned. This is platform dependent. Note also that since
GTimeVal stores the number of seconds as a glong, on 32-bit systems it
is subject to the year 2038 problem. Accordingly, since GLib 2.62, this
function has been deprecated. Equivalent functionality is available using:
|[
GDateTime *dt = g_date_time_new_from_unix_utc (time_val);
iso8601_string = g_date_time_format_iso8601 (dt);
g_date_time_unref (dt);
The return value of [glib.TimeVal.TimeVal.toIso8601|TimeVal.toIso8601] has been nullable since GLib
2.54; before then, GLib would crash under the same conditions.
Deprecated: [glib.TimeVal.TimeVal|glib.TimeVal] is not year-2038-safe. Use
g_date_time_format_iso8601(dt) instead.
Returns: a newly allocated string containing an ISO 8601 date,
or `NULL` if `time_` was too large
