Google My Business offers support options on its website, and now it may even show the opening hours of those support channels. Here is a screenshot from Usama Ali Twitter displays this support feature.
Its Google My Business Support page, once you have contacted and contacted the support agent, it may show you the opening hours field:
You’ll see support hours for each method today, tomorrow, or the next day, “show all” times, and a time zone.
I think this is useful when you need support and are not in the same time zone as Google Support.
