Riddle: If it is 4 Z in Boston then what Z time is it in Los Angeles?
Answer to Riddle: All locations on Earth have the same
Z time at any one time. Z time
standardizes time for all locations on earth. When it is 4 Z in Boston it is 4 Z
everywhere. The time that is different is the local time. When it is 11 pm in
Boston it is 8 pm in Los Angeles. The most common incorrect answer to this
riddle is 1 Z. When the 12 Z sounding is taken, all balloon stations
launch to get upper air data at the same time. When using Z time it is easier to have something done
at the same time at various locations since no adjustment to time zones is needed. All locations
on Earth use the time at the prime meridian for Z time.
