GMT used to be defined based on astronomical observations but is now used as a synonym for UTC. UTC is based on TAI, which is a timescale based on atomic clocks, but with leap seconds added when appropriate to keep UTC in sync with the earth's rotation and astronomical observations. See http://www.faqs.org/faqs/astronomy/faq/part3/section-4.html for more information on various time standards. --=20 <Insert your favourite quote here.> Erik Trulsson ertr1013@student.uu.se
