Just been messing about with the date functions, and there appears to be an inconsistency when adding a month modifier. I'm running Fedora 10.
[root ~]# sqlite3 SQLite version 3.5.9 Enter ".help" for instructions sqlite> SELECT date('2001-03-31'); 2001-03-31 sqlite> SELECT date('2001-03-31', '+1 month'); 2001-05-01 sqlite> SELECT date('2001-03-31', '+31 day'); 2001-05-01 sqlite> SELECT date('2001-03-31', '-31 day'); 2001-02-28 sqlite> SELECT date('2001-03-31', '-1 month'); 2001-03-03 sqlite> SELECT date('2001-03-31', '-28 day'); 2001-03-03 sqlite> From: http://www.sqlite.org/lang_datefunc.html "Thus, for example, the data 2001-03-31 modified by '+1 month' initially yields 2001-04-31, but April only has 30 days so the date is normalized to 2001-05-01." When I add '+1 month' to the example data, the example date has 31 days added to it. Which is correct. When I subtract '-1 month' the date only gets 28 days subtracted from it. Surely adding or subtracting a month modifier to a date should be the same number of days in each direction?
