function to_iso8601(): String {
    // Gjs wrapper for g_time_val_to_iso8601()

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.DateTime.prototype.format or GLib.strdup_printf if a different variation of ISO 8601 format is required.
