TimeVal.toIso8601

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 glib.date_time.DateTime.format or glib.global.strdupPrintf 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 glib.time_val.TimeVal 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.time_val.TimeVal.toIso8601 has been nullable since GLib 2.54; before then, GLib would crash under the same conditions.
