Vegas will accept a stereo bwf via file | import. The bwf will be dropped on the timeline at the point that matches the timestamp in the header of the bwf file. The timestamp will also be visible in the clip properties | media dialog.
Polyphonic bwf (more than stereo, such as output from a Sound Devices 744T or other multichannel recorder) must be split before use in Vegas. Fostex has a freeware splitter on their site called
BWF Manager that will tear down a polyphonic file into 1ch. bwfs.
Audacity is a freeware audio editor that will open BWF and export as wav, losing timestamp in the process.
