Moved `SYSTEMTIME` structure and related `kernel32` API calls, `SystemTimeToFileTime` and `CompareFileTime` helper functions from `test/test_storage.py` to `test/time_structs_helper.py`. This improves modularity and reusability of time-related utility functions within the test suite.
This commit introduces a new test class to `test/test_rot.py`. It verifies the functionality of `NoteChangeTime` and `GetTimeOfLastChange` by setting and retrieving the last change time of a registered COM object.
It verifies the functionality of `IMoniker.GetTimeOfLastChange` for file monikers by creating and modifying a temporary file and asserting that the `FILETIME` returned by `GetTimeOfLastChange` reflects the modification.

Overview
This pull request refactors time-related utility functions into a dedicated helper module and introduces new tests for time-sensitive operations within COM monikers and the Running Object Table (ROT).
These changes enhance the modularity of the test suite and improve the coverage of COM interaction capabilities concerning object lifetime and modification timestamps.
Enhanced Test Suite Modularity
Centralized Time-Related Utilities
The
SYSTEMTIMEstructure and associatedkernel32API calls, along with helper functionsSystemTimeToFileTimeandCompareFileTime, have been extracted fromtest/test_storage.pyinto a new, dedicated module:time_structs_helper.py.This improves the organization and reusability of time-related utilities, making the test suite cleaner and easier to maintain.
Verified Moniker Last Change Time Retrieval
New tests have been added to
test/test_moniker.pyto specifically validate theIMoniker.GetTimeOfLastChangemethod.This test ensures that when a file moniker's underlying file is modified, the
GetTimeOfLastChangemethod accurately reflects the updated modification timestamp.Accurate Running Object Table Time Management
Tests for
IRunningObjectTablehave been expanded intest/test_rot.pyto cover theNoteChangeTimeandGetTimeOfLastChangemethods.These tests verify that the ROT correctly records and retrieves the last change time of registered COM objects.
