1115  * A FILETIME is a 64-bit integer, giving the time since Jan 1, 1601,

1120  * file listings). This means it's the GMT you get by taking a local time
1121  * and adding the server time zone offset.  This is NOT the same as GMT in
1122  * some cases.   However, we don't know the server time zone, so we don't
