rubber-time
Rubber-time is the English translation of the Indonesian phrase 'Jam Karet'. It literally translates as a period of time which is made of rubber or elastic. There is a general acceptance that people will be late. Someone does not appear on time, or is late - shoulders are shrugged. "Oh well, it's rubber time."
