Just casting about for potential meridian locations that might explain the 12.5 minute difference. Maybe the central longitude of France is 12.5 minutes(of time, 3 1/8th degrees of longitude) from Greenwich? (like India's time zone being on the half hour). Things get done for funny reasons: After all, the physical size of France is why ATM "cells" (packets) are 53 bytes (48 byte payload) instead of either 32 byte or 64 byte payloads. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
