Checking Merchant Time?

Is it possible to check your Merchant Time or when does a merchant expire?

The description says it stays up for 24 hours, but I remember sleeping and getting on about 12-16 hours later and my shop was closed?

 

There isn't like that AFAIK. Check the server time and write it down somewhere everytime you open your store again.

 

So the shop does close every 24 hours?

 

Yup

 

Heads up that if there was a server check while you were sleeping, your shop would have been closed. That might explain why it was closed before the 24 hour mark!
