27.4.5.6 The format_time() Function
As of MySQL 8.0.16,
format_time() is deprecated
and will be removed in a future MySQL version. Applications
that use it should be migrated to use the built-in
FORMAT_PICO_TIME() function
instead. See Section 12.22, “Performance Schema Functions”
Given a Performance Schema latency or wait time in
picoseconds, converts it to human-readable format and returns
a string consisting of a value and a units indicator.
Depending on the size of the value, the units part is
ps (nanoseconds), ns
(nanoseconds), us (microseconds),
ms (milliseconds), s
(seconds), m (minutes),
h (hours), d (days), or
w (weeks).
Parameters
picoseconds TEXT: The picoseconds value to format.
