Describe the bug
Both Parse DateTime and Translate DateTime have a default input date and time of DD/MM/YYYY HH:mm:ss.

If the user loads a recipe with a different input (e.g. YYYY-MM-DD HH:mm:ss) this will be ignored and the original DD/MM/YYYY HH:mm:ss will be used instead.

Duplicate of #646 but this issue also includes the Parse DateTime operation which is also affected.

To Reproduce

Load the following recipe:

[{"op":"Parse DateTime","args":["Standard date and time","YYYY-MM-DD HH:mm:ss.SSSSSS","UTC"]}]

The default input will be DD/MM/YYYY HH:mm:ss and not YYYY-MM-DD HH:mm:ss.SSSSSS

Expected behaviour
The input should be the value from the recipe.

Thanks! Please keep up the good work.
