Interesting option. I think my choice is between separate day and sub- day 32-bit unsigned integers, text, and this 64-bit float option. I'm not clear, though. Did you mean to store double precision numbers where the seconds are the units (I assume this) or where the days are the units? And what do you think of the other option? -- http://mail.python.org/mailman/listinfo/python-list
