Arduino + Pico + SD card

When compiling the SD lib in Arduino, the Pico compiler issues the following warning:

\Arduino\libraries\Time-master/time.h:1:2: warning: #warning "Please include TimeLib.h, not Time.h. Future versions will remove Time.h" [-Wcpp]

Who is actually fixing this?

best regards!

Which 'Pico Compiler' ?

Link needed.

Then raise an issue on that Github page, the author of that complier is probably supporting it, for free.

Arduino have not released a plug in core for the Pico as yet.
