Convert time_t to System::DateTime ???

I need to convert time_t to System::DateTime. All of the examples that
I found are either in C# or in the obsolete managed C++ syntax. What
is the current syntax for converting a (probably 64 bit) time_t value
to System::DateTime ???

time_t t = ...;
long long filetime = t * 10000000LL + 116444736000000000LL;
DateTime datetime = DateTime::FromFileTimeUtc(filetime);
Console::WriteLine(datetime.ToString());

Here is the answer that I derived:

System::DateTime time_tToSystemDateTime(time_t tt)
{
tm* timeptr = gmtime(&tt);
DateTime sdt(timeptr->tm_year + 1900, timeptr->tm_mon + 1, timeptr-

Quote:

>tm_mday, timeptr->tm_hour, timeptr->tm_min, timeptr->tm_sec);

return sdt;
}

Here it is again, (Hopefully with better formatting)

System::DateTime time_tToSystemDateTime(time_t tt)
{
tm* timeptr = gmtime(&tt);
DateTime sdt(timeptr->tm_year + 1900,
timeptr->tm_mon + 1,
timeptr->tm_mday,
timeptr->tm_hour,
timeptr->tm_min,
timeptr->tm_sec);
return sdt;
}
