TimeVal

Deprecated since version 2.62: Use DateTime or guint64 instead.

class TimeVal(*args, **kwargs)

Constructors:

TimeVal()

Methods

class TimeVal

add(microseconds: int) → None

Adds the given number of microseconds to @``time_.`` microseconds can also be negative to decrease the value of @``time_.``

Deprecated since version 2.62: TimeVal is not year-2038-safe. Use guint64 for representing microseconds since the epoch, or use DateTime.

Parameters:: microseconds – number of microseconds to add to time

from_iso8601(iso_date: str) → tuple[bool, TimeVal]

Converts a string containing an ISO 8601 encoded date and time to a TimeVal and puts it into @``time_.``

iso_date must include year, month, day, hours, minutes, and seconds. It can optionally include fractions of a second and a time zone indicator. (In the absence of any time zone indication, the timestamp is assumed to be in local time.)

Any leading or trailing space in iso_date is ignored.

This function was deprecated, along with TimeVal itself, in GLib 2.62. Equivalent functionality is available using code like:

GDateTime *dt = g_date_time_new_from_iso8601 (iso8601_string, NULL);
gint64 time_val = g_date_time_to_unix (dt);
g_date_time_unref (dt);

Added in version 2.12.

Deprecated since version 2.62: TimeVal is not year-2038-safe. Use new_from_iso8601() instead.

Parameters:: iso_date – an ISO 8601 encoded date string

to_iso8601() → str | None

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 format() or 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, None 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 to_iso8601() has been nullable since GLib 2.54; before then, GLib would crash under the same conditions.

Added in version 2.12.

Deprecated since version 2.62: TimeVal is not year-2038-safe. Use g_date_time_format_iso8601(dt) instead.
