What does "MY Swiss Time is Running out" mean?

The Deep Purple song titled Smoke On the Water uses the words "Swiss time is running out" (close enough) to describe the fact that a scheduled show was at risk of being canceled because "Some stupid with a flare gun, burned the place to the ground" and a new place had to be found quickly.
The song describes how the show went on thanks to some last minute thinking. Good song!

Deep Purple? I think it ment that they had limited time to finish what they were going to do and the deadline was approaching. The word "MY" wasn't in the song.
