MariaDB starting with 11.0.2

Introduced in MariaDB 11.0.2




Given a time in picoseconds, returns a human-readable time value and unit indicator. Resulting unit is dependent on the length of the argument, and can be:

  • ps - picoseconds
  • ns - nanoseconds
  • us - microseconds
  • ms - milliseconds
  • s - seconds
  • min - minutes
  • h - hours
  • d - days

With the exception of results under one nanosecond, which are not rounded and are represented as whole numbers, the result is rounded to 2 decimal places, with a minimum of 3 significant digits.

Returns NULL if the argument is NULL.

This function is very similar to the Sys Schema FORMAT_TIME function, but with the following differences:

  • Represents minutes as min rather than m.
  • Does not represent weeks.
