Show more units and hints as help to know what to input

[hpvd]

A point a first time user (like me) would have helped a lot to set up the very first custom alert:
show more unitsand hints for format and type of input needed on all places where to input anything

• number: 3,000.5? 3000.5? 3000,5? 3000,500?
• duration: seconds? minutes? hours?
• time: hh:mm? hh:mm:ss?
• date: dd.mm.yyyy? dd.mm.yy? mm.dd.yyyy?

simple example for type problem:
