RemoteAttacher unit tests timezone sensitive, underlying bug? about rdmp

[jas88]

@JFriel example here - failed around 6pm Pacific Time (where I think Github's VMs live), early morning the next day UTC. https://github.com/HicServices/RDMP/actions/runs/9294965423/job/25581113234#step:12:1555

@jas88 do you have an example of these failing tests? From a look at the code, I'd guess it's to do with trying to load 'future' data?

[jas88]

Past, but not always far enough in the past - "2 days ago" sometimes becomes "1 day ago" and causes the time window tests to fail ("expected 2 rows but got 3"). It showed up on the Dependabot PR for Microsoft.Test.Sdk, then they passed when manually re-run a few hours later, because "now" was the same date for both timezones.

Maybe I'll try a specific test for that with a time/date just before and after midnight to catch it reliably.
