It doesn’t depend on the time. The return test just has to be taken in the three days before. Gov website gives the example of a flight to UK on Friday can be done Tues, Weds or Thurs
Here’s the official text…
“Taking your test in the UK before travel
If you are returning to the UK within 3 days, you can use the result of a COVID-19 test that you take in the UK before you travel. You must use a private test provider for the test and not an NHS test.
The service on which you will arrive back in the UK must set off for the UK within 3 days of when you took the test.”
