Sounds like problem is coming from alternator; either charge indicator circuit faulty, or it is OK and the alternator is in fact not charging properly.
By clock flashing I presume you mean the ":", which ticks of the seconds, rather than the actual clock illumination.
If you paid to have bat/alt checked and new battery installed I would go back to shop that did it.
