Description
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 thanm
. - Does not represent weeks.
