The time an order was created should be displayed the same regardless of the Mostrod configuration used.
When an order is newly created, it should say: "a moment ago".

Currently, when using the default Mostrod, it displays correctly because that Mostrod uses expiration_hours = 24. However, if I change the Mostrod instance and it uses a different expiration_hours, the app displays it incorrectly.

These orders were created just now and should say just now, but times are wrong

1. if the instance I'm using uses expiration_hours > 24 hours the app displays the time in the future.
   In this case expiration_hours = 40 it displays "16 hours from now"

2. if the instance I'm using uses expiration_hours < 24 hours the app displays the time in the past.
   In this case expiration_hours = 20 it displays "4 hours ago"
