Additional information

I was trying to run working code from one of my esp32 nodes on a pico w. I'm guessing that the function strptime has not been implemented in the rp2040 platform.

On my esp32 node, this code displays the countdowns of running timers from Home Assistant on an oled display. I wanted it running on the pico that has the start/stop buttons for those timers. If the strptime function is implemented, that would be a step towards parity with the esp32 code.

should this actually be filed against maxgerhardt/platform-raspberrypi instead?
