What is the exact information in SW canon regarding the speed of traversing the entire galaxy?

An excellent answer by @Daniel Bingham for " Was the Millennium Falcon too slow? " stated:

Even with a well traveled hyperspace route the fastest ships, such as the Millennium Falcon, would take several months to traverse the whole diameter of the galaxy.

Elsewhere the Galaxy was quoted as being 120,000 light years in diameter. ... Using that we can find that a class 1/2 hyperdrive would travel at about 28 light years per hour.

To which the following comment was posted:

@Daniel your in-edit calculations are off by a double order of magnitude... the travel times for crossing the galaxy in current canon are in double digit hours... not triple digit days. WEG got it wrong in SW 1E, and LFL made them change it later. But then, as nick notes, Sci-Fi Writers have no sense of Scale. ? aramis May 18 '11 at 17:44

Question:

What exactly is the canon source for the information in the comment? ("the travel times for crossing the galaxy in current canon are in double digit hours")
