To make things easier for other Snappers to check out your blocks, could you put them in an empty project and publish it on the normal site?
Lots of Snappers don’t have access to github and downloading/importing xml files is a lot more work at our end 
I agree that users might want to tweak the time format, but doing it as command blocks setting global state doesn’t seem very Snap!pish; why aren’t these reporters that report the time? Also, I don’t understand how “PM or AM detection” differs from “24-hour clock toggle.” (Since you posted only a screenshot, not a smart pic or a project link, I can only guess about what these blocks do.)
this isn’t your topic; and I don’t see ant time blocks in the op’s project. Maybe I am missing something
why not just use reporters?
You might want to use $arrowRight / $arrowLeft instead of -> / <-:
sorry for basing it off of ligatures, it will now use $arrowLeftThin and $arrowRightThin once I update it.
I used ligatures because the Snap! arrows don’t look right
OK!
added some on the project
oops
