Neither timezones nor dst impact length of the mean solar day.

TAI is some 35 seconds ahead of UTC this point. and will continue to
diverge in a fashion which is not sufficiently predictable that you can
know over the long term.

Not using utc as the timebase is certainly possible, gps does that for
example.

Apps are buggy sounds like a really poor excuse for doing so.
