Walmart has now joined a growing list of grocery store chains that have changed their operating hours in response to the coronavirus outbreak.

Walmart announced all of its stores, including Neighborhood Markets, will be open from 6 a.m. to 11 p.m. starting Sunday and until further notice.

The chain says this will give employees more time to clean stores and restock shelves.

Publix says as of Saturday, its stores will close two hours earlier at 8 p.m. for the same reasons.

Its stores will also alter operations for similar reasons with 24-hour locations closing at midnight for six hours.
