FWIW, "timer" is a dryos object.
Yes. DryOS on the a470 has 0 of those (as "maximum"), I have no idea how they are related to the successors of the various timer and hp timer functions found in VxWorks cameras. These functions are located by the sigfinders, but are not documented yet.
Hmm, yes D10 has 0 as max, elph130 has 4, but I haven't seen them in use.
