fix: set last access time with unspecified date time kind - #879
Conversation
This fixes an iconsistent DateTime conversion in the LastAccessTimeUtc setter by adding explicit conversion to local time. This fixes a conversion error that occurred when a value was passed with DateTimeKind.Unspecified.

Thanks for your work @xtopaz!

Should we also do this for the other *TimeUtc properties?

Not sure whether ToLocalTime is correct here. I think we rather want something like this: https://github.com/dotnet/runtime/blob/96d1c8e3ba4bc94afdcf15ee2896a3bc984820e7/src/libraries/System.Private.CoreLib/src/System/IO/FileSystemInfo.cs#L108

@fgreinacher Sorry for the late reply, just got back from vacation.
All other *TimeUtc properties already contain the ToLocalTime call. This way the behavior has been unified.
File.File.GetUtcDateTimeOffsetcannot be used because it is internal. However, this behaves analogously to the proposed implementation, since it takes Utc for DateTimeKind.Unspecified.
To be more precise, the preliminary conversion using ToLocalTime for values with DateTimeKind.Unspecified assumes UTC. The subsequent implicit conversion to DateTimeOffset then takes the time zone into account correctly. Thus the timestamps behave analogously to those in System.FileInfo.

@fgreinacher I've incorporated the recent changes from #875 and all test look fine.

Obsolete by #875. |
This fixes a missing
ToLocalTimeconversion in theMockFileInfo.LastAccessTimeUtcsetter, which leads to inconsistent results when dealing withDateTimevalues havingDateTimeKind.Unspecified.
