Calc date auto-conversion

LO Calc used to accept a raw cell entry like “1sep15” and automatically convert it to
the user-specified date format (ie. “15/09/01”) as soon as I hit [enter].

I haven’t been able to find a way to restore this functionality in LO calc version 4.4.3.2 on Linux.

Is there a way to re-enable it?
