CentOS release 5.8 (Final) - Linux mdp01r.prod.marinsw.net 2.6.18-308.11.1.el5 #1 SMP Tue Jul 10 08:48:43 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
Description
UNIX_TIMESTAMP() reports a decimal value when date string specified. Verified to work different on MySQL 5.5.9 (non MariaDB)
This bug was filed directly to maria-developers @ launchpad.net list too (using mysqlbug), but didn't get any response, so filing it here instead.. Can you guys verify if this is an issue or a "feature", and also cancel the launchpad.net list request?

More examples:
MariaDB [test]> SET @@timestamp=UNIX_TIMESTAMP('1970-01-02 03:04:05.123456'); SELECT @@timestamp; SELECT FROM_UNIXTIME(@@timestamp); |
Query OK, 0 rows affected (0.00 sec) |
+--------------+ |
| @@timestamp | |
+--------------+ |
| 86645.123456 |
|
+--------------+ |
1 row in set (0.00 sec) |
+----------------------------+ |
| FROM_UNIXTIME(@@timestamp) | |
+----------------------------+ |
| 1970-01-02 03:04:05.000000 |
|
+----------------------------+ |
1 row in set (0.00 sec) |
The expected result is to preserve the fractional digits .123456
The same problem happens with TIME() and TIMESTAMP().

These functions should be fixed to take into account the number of decimal
digits of the arguments.
