Convenient input (and output) of time in hours, minutes and seconds in Prime

Hello!

I'm doing an electrical engineering calculation in Prime 3.0 which amongst other parameters involves a timespan.

This timespan is rather lengthly (tens of hours), so having input using flat SI second is really a mess.

So currently I have to use an intermediate engineering calculator to convert stopwatch readout to hours.

Is there a way to have Mathcad Prime to accept human style timespan expressed in HH:MM:SS?

Thank you.
