Allow time input for a transaction to be optional

I understand this suggestion may not be received positively by the developer reading this, but I'm equally frustrated that somehow one of my banks doesn't disclose the timing of every transaction. In my case, incoming transfer or withdrawal transaction has no time.

I don't know what to do. If I set a random timing, it's kinda misleading. So I set it as 12 AM (00:00) for now, but I prefer the app to indicate me time is undefined for those particular transactions so they wouldn't be mixed with transactions that were really done at 00:00
