* Corrected the macro for comments on the test file. * Added current_date (utcnow()) variable available for template macros. * Removed unnecessary datetime import from macros file. * Regenerated all practice exercise test files to add timestamp. * Changed `datetime.now(tz=timezone.utc)` to `datetime.now(tz=timezone.utc).date()` * Second regeneration to remove `timestamp` and just keep `date` for test files. [no important files changed]
