@iSazonov I tend to agree that this seems like a bug that should be fixed in .NET

Looking through the .NET source, they only use CLOCK_BOOTTIME to calculate the start time of processes and is not public. So it seems the best option is to P/Invoke the API on non-Windows.

This doesn’t work on all platforms.

Best option is to request new API in .Net System.Environment.Uptime. Until that, since it is not critical, we could add a workaround for Linux systems and use /proc/uptime.
