But Cassandra 1.1.7 is not fully CQL3, yet. Is it?
By default 1.1 is CQL 2
1.1 is CQL 3 beta and it not compatible with CQL 3 in 1.2. 
I do not think there are plans to bring CQL in 1.1 up to the CQL 1.2 spec. Though I may be wrong there. 

If you are using a higher level client it will be using thrift, and if you are not setting the timestamp the client will be doing it for you. 

In either case it's always good to have the clocks as syncronised as possible.

And thanks for your responses, Aaron and Vegard.
