mysql ERROR 1426 (42000): Too big precision 14 specified for column 'createDate'. Maxi mum is 6
===

guy. I have a strange trouble When I try create a table with timestamp type.

    create table `test`
     ( `time` timestamp(14) );

   *ERROR 1426 (42000): Too big precision 14 specified for column 'time'. Maximum is 6.*

I thought the `14` is a bytes lengths for storage. But it seems like the time precision.

Anybody can explain it ? I didn't find it in online documentation!
thanks
