Problem Description

When running tests on multiple machines and CI systems distributed around the globe, the system's time zone can cause inconsistencies in test results.

Solution: Using WithTimeZone

ApprovalTests provides a convenience class, WithTimeZone, to set a consistent time zone for a block of code. This ensures that all code within the block uses the same time zone, avoiding inconsistencies caused by different system time zones.

Here is an example:

try (WithTimeZone tz = new WithTimeZone("UTC"))
{
  // All code within this block will see the computer as being in the UTC time zone
}
// The computer's time zone will revert to previous setting here
