[markm]

In _msi.c, summary_getproperty() and summary_setproperty() raise an exception if the type being set/got is VT_FILETIME.

This issue is to track adding support for (or declining to support) FILETIMEs in msilib.SummaryInformation.GetProperty()/SetProperty().

I have included a patch which adds this support (with some basic tests).
Should this function accept/return datetime.datetime - or a timestamp (both require conversion anyway). I have used datetimes in my patch.

@Martin/Steve do you consider this enhancement request worth pursuing?

[iritkatriel]

msilib is deprecated as per PEP-594, so there won't be further enhancements to it.
