Glib::TimeVal is a wrapper around the glib structure GTimeVal.
The glib structure GTimeVal itself is equivalent to struct timeval, which is returned by the gettimeofday() UNIX call. Additionally this wrapper provides an assortment of time manipulation functions.

Returns a double representation of the time interval.
This member function converts the time interval, that is internally stored as two long values for seconds and microseconds, to a double representation, whose unit is seconds.
Glib::ustring Glib::TimeVal::as_iso8601 | ( | ) | const |
Returns an ISO 8601 encoded string, relative to the Coordinated Universal Time (UTC).
void Glib::TimeVal::assign_current_time | ( | ) |
Assigns the current time to the TimeVal instance.
Equivalent to the UNIX gettimeofday() function, but is portable and works also on Win32.
bool Glib::TimeVal::assign_from_iso8601 | ( | const Glib::ustring & | iso_date | ) |
Converts a string containing an ISO 8601 encoded date and time to a Glib::TimeVal and puts it in TimeVal instance.
iso_date | ISO 8601 encoded string. |
true
if conversion was successful.

Checks whether the stored time interval is positive.
Returns true if the stored time / time interval is positive.
