looks like this is coming from
concrete_time::TimeSpan::from_start_and_end_systemtime
which I believe I added
that's only used in the workunit store, something is trying to create a workunit with an end_time prior to the start_time
this is another thing that's in code that https://github.com/pantsbuild/pants/pull/10277 touches
still might be a good idea to add an explicit check for this
