Office Open and Closed Times

Hi there What would be the correct way to indicate if an office is open or closed (by using two images OPEN and CLOSED) according to the daily business hours? I have created an Entity with the following attributes: WeekDay OpenTime CloseTime The user’s time on the device needs to compare the date and time with the Objects in the Entity and simply display an Image to indicate Open or Closed

First, are you working in different time zones or can you assume a single timezone?

Second, Can you use server time instead?

(I would prefer server time over device time if possible. Device time can be off and can therefore show the wrong office open/closed state)
