19143: boards: common: stdio_cdc_acm: let tests wait a bit for serial port [backport 2023.01] r=kaspar030 a=kaspar030 # Backport of #19128 19144: shell/rtc: Fix out of bounds access; document error behavior [backport 2023.01] r=kaspar030 a=kaspar030 # Backport of #19141 ### Contribution description ### Testing procedure Should be trivial enough, especially as the difference is hard to spot interactively. On native, run the default example (and wait for the traffic to settle). Then, run ``` > rtc poweron > rtc settime 2022-01-01 00:00:00 > rtc settime 2022-99-01 00:00:00 ``` Both still work, but the latter doesn't access unassigned memory any more ### Issues/PRs references This fixes an issue that was submitted anonymously.
