This type of issue is a known limitation of Seat Licenses. UFT checks the date/time for tampering. If you continue to run the tests that change the date/time using a seat license, you'll continue to experience the issue and may even completely lock out the ability to use UFT, in which case you'd have to get a cleaning key from Micro Focus (https://softwaresupport.hpe.com/group/softwaresupport/search-result/-/facetsearch/document/KM01903662).

I recommend using a concurrent license when running this type of test because the date/time on the concurrent license server won't be changing, only the UFT client machine. So when you have to run this type of test, temporarily switch to a concurrent license server.
