Entrypoints:

• remainingTime returns the time the process could still execute
• ellapsedTime: returns elapsed 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.
