Incorrect value of $__unixEpochTo() macros

[imReker]

I set panel time shift to '1d/d' so the start and end time will be aligned with 0 o'clock. $__unixEpochFrom() expanded to 1632067200 => 2021-09-20 00:00:00, which is correct. But $__unixEpochTo() expanded to 1632758399 => 2021-09-27 23:59:59, 1 second ahead of the end time. Tried other data source like Prometheus, the time range is correct, which is 1632067200 to 1632758400.

Not sure why this is different, as I'm using range from the official API:

If anyone wants to have a look, I'd welcome a pull request!
