What is the unit of time in MySQL's slow-query log?

Question

I\'m looking at the slow query log from a drupal-based webapp, and have lines that look like this:

# Query_time: 3257  Lock_time: 0  Rows_sent: 272  Rows_exa

It's in seconds. The 'resolution of microseconds' means, that you can have up to microsecond precision after a decimal (although AFAIK it need a patch to actually write with such precision)
