What is the correct temperature of boiling water?

Most people will answer 100oC (212oF) and for the answer will be pretty much correct for most needs. However boiling point temperature depends on atmospheric pressure. The 100/212 answer is only correct for 760 mm pressure. On the tops of mountains or even in Denver and Calgary the actual boiling temperature is slightly lower. Climbers on Everest report that boiling eggs takes much longer decease of the lower boiling point.
