Fellow Shadow Watchers,
Can anyone tell me when (or if) the system of
International Time Zones was formally established/recognized and by what
authority? Did it just evolve from each country's individual needs and
interpretations or was there an international conference at some stage?
I have the British Admiralty World Time Zone Chart (5001) revised 1992
but the notes thereon give no indication of its origins.
The information is requested for the notes to accompany a public dial and
if anyone has this to hand it would save some urgent trawling through
reference material.
Thanks in anticipation,
Tony Moss
