title: EF Core open SQLite database generated from Azure MobileService
body: <p>I need to read a SQLite database which is synced from Azure SQL with MobileService. The problem is, in MobileService, it saves DateTime type as unixepoch, a double value, not in format of YYYY:MM:DD hh:mm:ss. </p>
  
  <p>So when EF Core accesses this column, it will throw an exception for wrong year, month, day format. I tried to use a <code>ValueConverter</code> in <code>OnModelBuilder</code>, but that's not helpful, exception happens before entering that function. </p>
  
  <p>My question is, in EF Core, is there a way to specify the DateTime format as unixepoch, or is there a chance to do the conversion manually?</p>
