-- Represents a precise time, with seconds and microseconds.
-- Similar to the struct timeval returned by the @/gettimeofday()/@
-- UNIX system call.
-- 
-- GLib is attempting to unify around the use of 64bit integers to
-- represent microsecond-precision time. As such, this type will be
-- removed from a future version of GLib. A consequence of using @glong@ for
-- @tv_sec@ is that on 32-bit systems @GTimeVal@ is subject to the year 2038
-- problem.
