I noticed an interesting little snippet in that paper about the Time Ball being dropped.
Branch Hydrographic Office USN Merchants Exchange, San Francisco, California, October 30 1900.
The time ball on the tower of the new Ferry building was dropped at exactly noon to-day - i.e. noon of the 130th meridian, or at 8 o'clock p.m., Greenwich time.
