Description

Now that we have both CpuTime and ElapsedTime, should we also have ElapsedTimeFrom?

History

#1 Updated by John Abbott about 3 years ago

Currently CpuTime and ElapsedTime return rational numbers (representing seconds).

There is a risk that if someone uses ElapsedTimeFrom with argument corresponding to a CpuTime value then a "meaningless" value may be produced.
One way to avoid this would be to use tags or records to encapsulate the values from CpuTime and ElapsedTime.... but that would not be backward compatible.

I'm tempted to reject this. Yes, there is the risk mentioned in the description, but it is not so serious -- if necessary, we can improve the documentation.
Currently, I cannot think of any great use for ElapsedTime... I suppose I must have added it for a reason...
