It's JDBC / ODBC escape syntax for timestamps.
http://java.sun.com/j2se/1.4.2/docs/guide/jdbc/getstart/statement.html#999472
http://support.microsoft.com/?scid=kb%3Ben-us%3B142930&x=9&y=15
The former is converted by the ODBC / JDBC driver to some DB specific
binary representation of a timestamp while the latter undergoes
conversion in the DB. I'd generally use the escape syntax as it is more
portable and not affected by session parameters that affect date formatting.
Kind regards
