Prerequisites

Are you running the latest version?
Can you reproduce the problem in the debug version?

Check and fill as appropriate:

I was running Aaru under Windows 10...
...using .NET Core 3.1...
...in 64-bit

Description

In the DateHandlers code, the last byte of the PVD is taken in but never used. Instead, it sets DateTimeKind.Unspecified. Of note, the timzone byte is 00 for UTC then adds or subtracts byte per 15 minutes of timezone offset, making UTC +00:1501and UTC -00:15FF`.

Exact command line used:

Aaru media dump E: B:\_TEMP\VS2.aif

Expected behavior:

PVD datetimes in the CICM sidecar to include timezone offset information

Actual behavior:

PVD datetimes in the CICM sidecar are correct, but lacking timezone offset information
