"bad date" from "touch" when using -t option

[jgurling]

Hi, I'm trying to use adb-sync with the -t option to preserve file datestamps. Running on Ubuntu 20.04, connected to OnePlus 5 via USB. See code output below - seems like it's calling "touch" command which is taking issue with value (or format?) 20190103.103814. Is this an issue with adb-sync, or something on my end?

Same here, because

adb shell 'touch --help' |grep -P '^-t'
-t	Set time to TIME (in [[CC]YY]MMDDhhmm[.ss][frac] format)

I monkey patched it by changing those two strftime templates accordingly:

time.strftime('%Y%m%d%H%M.%S'
