Show timestamp for calculation history

[Former user]

Many times I needed to refer to a calculation I did weeks ago, but can't remember when. It's good that SpeedCrunch shows previous calculations made, and there's even a History functionality, but they're both missing the date/time when the calculation was performed.

Ability to show timestamp of when a calculation was done, preferably a toggle that can switch on/off to show the timestamp in the main window and ability to customize how the date/time is displayed.

Simple request, I'd write this myself if I had time.
