Entrypoints:

remainingTime returns the time the process could still execute
ellapsedTime: returns ellapsed time since program start
kernelTime: returns the amount of time the process has spent in kernel mode
userTime: returns the amount of time the process has spent in user mode
cpuTime: returns kernel+user time

On Windows NT Time is expressed as the amount of time that has elapsed since midnight on January 1, 1601 at Greenwich, England.

On Unix time is expressed as the amount of time that has elapsed since midnight on January 1, 1970 at Greenwich, England.
