part that rounds up to exactly 1.0 second. The previous coding rejected input like "00:12:57.9999999999999999999999999999", with the exact number of nines needed to cause failure varying depending on float-timestamp option and possibly on platform. Obviously this should round up to the next integral second, if we don't have enough precision to distinguish the value from that. Per bug #4789 from Robert Kruus. In passing, fix a missed check for fractional seconds in one copy of the "is it greater than 24:00:00" code. Broken all the way back, so patch all the way back.
