Support configurable start time - emailable report #2476
This value is not very human readable, and this change adds a protected
Did you remember to?
The `EmailableReport2` class provides test start time values which are in millisecond value from the epoch (01/01/1970 00:00:00): - sample value `1610359715103` - GMT : January 11, 2021 Monday 10: 08: 35.103 - see `test-output/emailable-report.html` for start time report usage - see https://www.epochconverter.com/clock This value is not very human readable, and this change adds a protected method which can be overridden in sub classes to provide a more human readable version of the test start time (e.g. `2021-01-01 12:34:56`) Fixes #2459
