NAME
System_Clock - BSON Clock Abstraction
SYNOPSIS
int64_t bson_get_monotonic_time (void); int bson_gettimeofday (struct timeval *tv, #if defined(__SUNPRO_C) void *tz); #else struct timezone *tz);
DESCRIPTION
The clock abstraction in Libbson provides a crossâplatform way to handle timeouts within the BSON library. It abstracts the differences in implementations of gettimeofday(3) as well as providing a monotonic (incrementing only) clock in microseconds.
