URLs that are used for timestamping an AIR application?

Hi,

Due to recent IT policy changes, our build server can no longer access the internet freely. We have to provide a list of URLs that will be whitelisted then. Due to this, our build now fails with:

Could not generate timestamp: Connection refused

Is there somewhere a list of possible URLs that ADT will connect to do to the timestamping of the application?

regards,

Wim

PS: I know I can specify "-tsa none" as a temp workaround, but I don't want to release like that.
