ESPB website had post time at 6:24 P.M. EST all day long, complain to them.
I have no clue who "ESPB" is. I've been betting horses since before most people here were born. These days I print my info from Brisnet.
Equibase, which is the official database for the industry, also has the Post Time as 6:34. (See here)
But thanks for playing.
