Corrupt zoneinfo files on GW3/Tizen

I had an unexpected crash of my app.

My app retrieve the zone info from /usr/share/zoneinfo/Europe/Vienna.

After some investigation in the file system, i realized, that most of the tz-files are corrupt.

I'm not sure, if this is an error of the OS, or the memory chip of my Galaxy Watch 3 is broken. Unexpectedly, suddenly from one minute to the other, the files are broken. Without my intervention, no updates and so on.

On GW2 with same Tizen-Version the files are o.k. (Currently...)

Have someone the same experience?

Thank you.

(Plz, don't say me, i have to reinstall the OS -> I know, but i want to find the problem first)
