# cpuTime -- seconds of cpu time used since Macaulay2 began

## Synopsis

• Usage:
cpuTime()
• Outputs:
• , the number of seconds of cpu time used since the program was started

## Description

 i1 : t1 = cpuTime() o1 = 205.671843339 o1 : RR (of precision 53) i2 : for i from 0 to 1000000 do 223131321321*324234324324; i3 : t2 = cpuTime() o3 = 210.420458493 o3 : RR (of precision 53) i4 : t2-t1 o4 = 4.74861515400002 o4 : RR (of precision 53)

## Caveat

Under Linux, the cpu time reported is that consumed by the thread, but under MAC OS X, it is that consumed by the process.
