Ptolemy. Almagest
[p. 208]

The second, which Hipparchus too used, occurred in the twentieth year of that Darius who succeeded Kambyses, Epiphi [month XI] 28/29 in the Egyptian calendar [-501 Nov 19/20], when 6 1/3 equinoctial hours of the night had passed; at this eclipse the Moon was, again, obscured from the south 1/4 of its diameter. The middle of the eclipse was 2/3 of an equinoctial hour before midnight in Babylon (for the length of half the night was about 6 ¾ equinoctial hours on that date) and [hence] l 1/4 equinoctial hours before midnight in Alexandria.
