It's an hour before and an hour after the scheduled time in LTC where I live (Oregon) too.
However, don't rely on word of mouth; in fact, you'd do well to get a copy of your state's "Bible", AKA the rules and regs, and take it with you to bed, to meals, and when you need to "roost" in the bathroom, until you can cite them chapter and verse in your sleep!
Seriously........every DON in long-term care needs to be thoroughly familiar with her/his state's laws, because ignorance is no excuse when the surveyors walk in the building and cite the facility for violating some obscure rule governing paint chips in the janitor closet, for example. LOL
