Return the current wallclock timestamp, just like UNIX gettimeofday().
Add the specified time in microseconds to the specified timeval structure
Return the time difference between now and the specified timestamp
Compare the two timeval structs and return 0 when equal, negative when a < b, positive otherwise
Calculate the difference between the two specified timeval * structs.
Load the specified tv value and return it in usec. \since 0.9.7
Store the specified usec value in the timeval struct. \since 0.9.7
Subtract the specified time in microseconds to the specified timeval structure. \since 0.9.11
