Updated MySQL time handling code to react correctly on UTC leap second additions. MySQL functions that return the OS current time, like e.g. CURDATE(), NOW() etc will return :59:59 instead of :59:60 or 59:61. As a result the reader will receive :59:59 for 2 or 3 consecutive seconds during the leap second. This fix will not affect the values returned by UNIX_TIMESTAMP() for leap seconds. But note that when converting the value returned by UNIX_TIMESTAMP() to broken down time the correction of leap seconds will still be applied. Note that this fix will make a difference *only* if the OS is specially configured to return leap seconds from the OS time calls or when using a MySQL time zone defintion that has leap seconds. Even after this change date/time literals (or other broken down time representations) with leap seconds (ending on :59:60 or 59:61) will still be considered illegal and discarded by the server with an error or a warning depending on the sql mode. Added a test case to demonstrate the effect of the fix. |
