TIME[(fsp)]

A time. The range is '-838:59:59.000000' to '838:59:59.000000'. MySQL
displays TIME values in 'hh:mm:ss[.fraction]' format, but permits
assignment of values to TIME columns using either strings or numbers.

An optional fsp value in the range from 0 to 6 may be given to specify
fractional seconds precision. A value of 0 signifies that there is no
fractional part. If omitted, the default precision is 0.
