[MINOR] introduce now_ms, the current date in milliseconds

Browse Source 
This new time value will be used to compute timeouts and wait queue
positions. The operation is made once for all when time is retrieved.
A future improvement might consist in having it in ticks of 1/1024
second and to convert all timeouts into ticks.
