quick check of current URL to skip timepicker (#146462)

## Summary

We have some tests which set the default time but then also call
setAbsoluteTime in every test. This PR adds code in setAbsoluteTime to
quickly check if the desired start and end (from and to) times are
already set, and if so, just return. The end result should be less time
spent on functional tests. It could also reduce occasional flakiness
setting the time.
