Recovering original time zone from DateTimeOffset after conversion

Goal

Convert a local DateTime to DateTimeOffset in a .NET application and later determine which time zone originally produced the value.

Constraint

DateTimeOffset stores only an offset from UTC, not the originating time-zone identifier. DateTime does not expose whether a value is ambiguous or invalid; conversion depends on the active time-zone rules on the host machine and can vary with the installed .NET runtime and Windows time-zone data. Offset alone cannot reliably reconstruct the source zone across daylight-saving transitions.

Question

Is there a supported .NET mechanism to preserve or recover the original time-zone identifier through a DateTimeOffset conversion, or must applications store zone metadata separately?
