TOPIx - time

Hi guys silly question... I do know... but in different countries some things mean completely different

on TOPIx manuals in PDF there's always a clock pictogram with a value e.g.: 0.1, 0.5, etc.
Guess it is the time needed to do the job
Please tell me what does it mean? does 0.5 stand for half an hour? and 0.1 for 6 minutes?

Thanks in advance

My guess would be yes, as these are designed to use as installation guides for service departments which charge by billable hours for labour.

thank you

Needed some arguments against my dealers high valuation... That will do, I think...
