Can someone review the changes and approve the pull request?
There are very few changes, just one line not counting the auto-test. In terms of functionality, it only affects the date filtering with time and nothing else.

I added a more accurate setter for 'Kind' depending on TimeZoneInfo in the settings.
All tests are passing, and there are new tests.

private static DateTimeKind GetTargetDateTimeKind(TimeZoneInfo timeZone)
    {
        if (timeZone.Equals(TimeZoneInfo.Local))
            return DateTimeKind.Local;

        if (timeZone.Equals(TimeZoneInfo.Utc))
            return DateTimeKind.Utc;

        return DateTimeKind.Unspecified;
    }

DateTimeOffset dateTimeOffsetValue = (DateTimeOffset)value;
TimeZoneInfo timeZone = timeZoneInfo ?? TimeZoneInfo.Local;

dateTimeOffsetValue = TimeZoneInfo.ConvertTime(dateTimeOffsetValue, timeZone);

var dateTimeKind = GetTargetDateTimeKind(timeZone);

return DateTime.SpecifyKind(dateTimeOffsetValue.DateTime, dateTimeKind);

Could you please let me know how often you conduct releases and when we can expect a new version with this fix? Will we have to wait for a scheduled release for some time, or can a version with these changes be released earlier (perhaps as a release candidate or something similar)?
