Hi All,

We are trying to see if changing the system date(hardware clock) during 
sleep time of a process causes the process to exit abruptly or not. It 
seems when we use gettimeofday(), the process hangs but when we use 
clock_gettime(...,CLOCK_MONOTONIC) by defining USE_MONOTONIC in the 
attached c file the program works.
Can anyone tell me why gettimeofday() will cause the process to hang and 
why clock_gettime() will work?

Thanks in advance
Regards
