/**
* glk_current_time:
* @time: pointer to a #glktimeval_t structure.
*
* The current Unix time is stored in the structure @time. (The argument may not
* be %NULL.) This is the number of seconds since the beginning of 1970 (UTC).
*
* The first two values in the structure should be considered a single
* <emphasis>signed</emphasis> 64-bit number. This allows the #glktimeval_t to
* store a reasonable range of values in the future and past. The @high_sec
* value will remain zero until sometime in 2106. If your computer is running in
* 1969, perhaps due to an unexpected solar flare, then @high_sec will be
* negative.
*
* The third value in the structure represents a fraction of a second, in
* microseconds (from 0 to 999999). The resolution of the glk_current_time()
* call is platform-dependent; the @microsec value may not be updated
* continuously.
