calculated items with time (vfs.file.time)

[jnsvano]

Hi,
I have serveral vfs.file.time items, that are ok.
Now I'd like to create calculated item looking like this:
{host:vfs.file.time[/file].now(0)}-{host:vfs.file.time[/file].last(0)}, but always got an error "unsupported"
Could be something special with time items ?

Please try formula below.

now("host:vfs.file.time[/file]")-last("host:vfs.file.time[/file]")

Thank you, Atsushi, it's working.
