Noted in 5.1.63 changelog.

If the system time was adjusted backward during query execution, the
apparent execution time could be negative. But in some cases these 
queries would be written to the slow query log, with the negative
execution time written as a large unsigned number. Now statements
with apparent negative execution time are not written to the slow
query log.
