Date/Time Stamp 4 Hours Off

[michaelcoles]

Hi, thanks for the great tool. I'm playing around with it and I noticed a couple of issues. I'll file them as separate bugs for you. The first issue is that when I create an MSG file using the sample testing tool you provided, it seems to subtract 4 hours from the current time. As an example, I chose March 1, 2017 with the datepicker control, and saved at 12:06:39 PM. When I opened the file it indicated the creation date of March 1, 2017 at 8:06:39 AM. Not sure if the issue is with the datepicker control or elsewhere.

That can be possible, still need to finish some things in this library but the lack of time is the biggest problem :-)

No worries. If it helps it seems to be happening around line 265 in Properties.cs in the AddProperty() method. This line:

            case PropertyType.PT_SYSTIME:
                var fileTime = ((DateTime)obj).ToFileTimeUtc();
                data = BitConverter.GetBytes(fileTime);
                break;

If I change it to this, it works:

            case PropertyType.PT_SYSTIME:
                var fileTime = ((DateTime)obj).ToFileTime();
                data = BitConverter.GetBytes(fileTime);
                break;

The odd thing is that the time conversion to UTC should add +4 hours from my time zone, not subtract 4 hours (I'm in U.S. EST). Looks like that might be a bug in a .NET Framework method.

Well I have to look into that. Maybe that I'm doing something wrong in the code.

Your code looks good, it's just that last conversion to UTC that seems to be throwing it off.
