Language may have special (typically dial-derived) ways of giving minute-precise clock times. It appears that in some languages, the only way to do this is in a purely additive way, with the hour and the minutes in a sequence that mirrors the digital time format: Thus, Mandarin Chinese has liù diăn wŭ-shí wŭ [six hour fif-ty five] for 6:55.
But many languages are like English, allowing subtractive clock-time expressions such as five to seven, or they allow fraction words such as quarter and half (half past six, quarter to seven). Colloquially, these are often still preferred to digital-clock-derived expressions (e.g. six fifty-five), but with the ever increasing spread of digital clocks, it is probably not overly pessimistic to say that the colloquial clock-time conventions are “endangered subsystems” (Wohlgemuth & Köpl 2005) in all languages, including English.
