Confirming \timing output

["Gauthier, Dave" <dave.gauthier@xxxxxxxxx>]

With \timing set on, I run an update statement and it reports....

 

Time: 0.524 ms

 

Is that really 0.524 ms?  As in 524 nanoseconds?

 

Also, is this wallclock time or some sort of indication of how much cpu it took?

 

Thanks for any answers !
