Action expr. values

[den_crane]

I made item: (sysUpTimeInstance)

Type of information: Numeric (Float)
Units: s
Custom multiplier: 0.01

In Last value it evaluates as: 58m20.87s (3h42m6.78s, etc)


And I made action with body:

{{HOSTNAME}:{TRIGGER.KEY}.last(0)}

But in letters it evaluates as: 2.27 Ks (156.77 Ks).
How make a date (58m20.87s) from 2.27 * 1000s?
