Is there a function to get last N 'changed' values? For example:
There is an item vfs.file.time which checks file time every 30 seconds. File could change every 10 or 5 or 7 minutes. I need to compare last value with previous *changed* value.
I need something like last(N) but N should not last stored values, but last *changed* values. Is there something like this?
