Polly,

I do not know the best way to explain how it works, but I know why it works.
In TMG, regular dates are stored using digits for the year, month, and day,
in that order. For date rages, both dates are stored. I'll omit some of the
details, but you can think of it like this:

"1 Jan 1870-2 Jan 1870" is stored as "1870 01 01 1870 01 02".

I added spaces to make it easier to see the parts (year first, then month,
then day, and then those fields again for the second of the two dates).

So, the values for the three dates above are:

1870 01 01 1870 01 02
1870 01 01 1870 01 03
1870 01 01 1870 01 04

The values are exactly the same for the first 15 characters, but the last
character differs. When TMG (or Second Site) sorts the events, the last
character will determine the sequence.
