Evening types may no longer serve as our midnight lookouts, but their intelligence, creativity, humor, and extroversion are huge potential benefits to the organization.

Hoe laat is het nu echt?

Greenwich Mean Time:
Utrechtse Middelbare Tijd:
Midden-Europese Tijd:
Midden-Europese Zomertijd:
De Utrechtse Middelbare Tijd (UMT) of Zonnetijd, zoals die in de negentiende eeuw werd bepaald, hoort bij de Meridiaan van Utrecht: 5° 07' 46.67" Oosterlengte. Deze zou dus 5° 07' 46.67" x 4 minuten = 5,1296° x 4 minuten = 20m31,67s moeten voorlopen op de GMT. In de winter is het verschil tussen UMT en MET zo'n 40 minuten, in de zomer 1 uur en 40 minuten.
