Please for the heaven sake, change the time effort shorthand m to minutes rather then representing months

What is the challenge?

The mistake of confirming 30m as 30minutes and instead logging effort 660d is very challenging.

What is the impact?

Incorrect time log, and even if it is deleted, it screws up the iteration retrospective, when it's corrected after iteration has been closed.

Describe your idea

m should represent minutes, together with min, and month should be represented as something as mo (i'd be curious if anybody is using month units for time effort, as this is usually used on reqs instead of the features or epics, which are usually configured to accumulate the estimate and worked effort from assigned items).
