| Description | The text telemetry files produced by mpseventcnv on Windows have the top 32 bits of every event clock value printed as zero. |
| Analysis | we fprintf with %016lX, so the fprintf is using the 'long' type which with Visual Studio is 32 bits. Use %016llX instead, so fprintf uses 'long long', which is the appropriate 64-bit type for the EventClock values. |
