Describe the bug

Failing tests:

• Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerTests.ExpirationAndIssuedWhenMinOrMaxValue
• Microsoft.AspNetCore.Authentication.JwtBearer.JwtBearerTests_Handler.ExpirationAndIssuedWhenMinOrMaxValue

Some unit tests in Identity are failing if local timezone on developer's machine is to the east of UTC, due to DateTime.MaxValue is locale-specific. For example, if my local machine is at UTC+4, the exp value written to generated JWT is 253402286400 (which stands for 9999-12-31T20:00:00.0000000Z), while expected value was 253402300800 (standing for 9999-12-31T23:59:59.9999999Z). If I set local time zone for UTC or any "UTC-minus-N" timezone, the value written to JWT is expected and same for any such time zone.

Need to add explicit DateTimeKind UTC and immediate conversion to UTC when parsing, since the actual time value (9999T23:59:59+00) is unrepresentable in local timezone.

Expected Behavior

No response

Steps To Reproduce

Run tests with local time zone "UTC plus N", for example UTC+4
