Topic: Host Query for kAsioCanTimeInfo doesn't return ASE_SUCCESS

I'm using a Fireface UC and writing an ASIO host.

Is there a reason why querying kAsioCanTimeInfo doesn't return ASE_SUCCESS?
Does the device really not support it or is it just playing it safe for compatibility reasons or so?

The device seems to be able to use bufferSwitchTimeInfo when i tell it that my host would like to use it (returning 1 in asioMessages() for kAsioSupportsTimeInfo), suggesting that it supports it nevertheless?
