bson_get_monotonic_time − System Clock
BSON Clock Abstraction
int64_t bson_get_monotonic_time (void); int bson_gettimeofday (struct timeval *tv);
The clock abstraction in Libbson provides a cross−platform way to handle timeouts within the BSON library. It abstracts the differences in implementations of gettimeofday() as well as providing a monotonic (incrementing only) clock in microseconds.
