SWbemDateTime.UTC may return values outside the range of -720 to 720 without error

[BozhanL]

Run the following vbs in New Zealand timezone on Windows 11.

Set dateTime = CreateObject("WbemScripting.SWbemDateTime")
dateTime.SetVarDate Now
Wscript.Echo dateTime
Wscript.Echo dateTime.UTC

Output:

20260213135921.000000+780
780

Test with high offset.

Set dateTime = CreateObject("WbemScripting.SWbemDateTime")
dateTime.Value = "20260213024238.000000+900"
Wscript.Echo dateTime
Wscript.Echo dateTime.UTC

Output:

20260213024238.000000+900
900

Pull request overview

This PR updates the documentation for SWbemDateTime.UTC to reflect observed behavior where reading the property can return timezone offsets outside the documented -720..720 range without raising an error.

Changes:

• Clarifies that the -720..720 range is enforced on writes, while reads may return values outside the range.
• Updates the “Error codes” section wording to scope errors to setting the UTC property.
