A variant of the 12-hour clock is also used, in particular in informal speech for approximate times.

For example, "Fine, thank you" is Guet, merci; with guet being the German word for good/fine, while merci is from the French "thank you".

In addition, there are many pronunciation differences which separate Swiss-German from either language.

For example, the diphthong in Swiss-German "guet" versus the monophthong in High-German "gut".

You are unlikely to have to learn Swiss-German, as all German-speaking Swiss educated in modern day schools are also able to speak standard German.

Systematic use of the 24-hour clock by German TV announcers, along with the proliferation of digital clocks, may have been a significant factor in this development.

In Switzerland, only the 12-hour clock is used in speech.

There are two variants of the 12-hour clock used in spoken German regarding quarterly fractions of the current hour.

One always relates to the next full hour, in other words, it names the fraction of the currently passing hour.

Just as with the date format, leading zeros seem to be less common in Germany than in Austria and Switzerland although the Austrian Standard ├ľNORM also recommends the zero only for table-form dates like "Abfahrt: Uhr" and not for running text.
