Time.demongoize could attempt to demongoize string input in various formats, for example:

Time.demongoize("2022-04-20T17:20:04.75-07:00")
  #=> undefined method `getlocal' for "2022-04-20T17:20:04.75-07:00":String (NoMethodError) 

The `#demongoize` method is expected to work for a variety of input types, not just Time, as the user may have stored strings in their database previously then changed the field type.
