error: 'DateTimeFields' has not been declared

[MaurinElectroTextile]

Trying to compile but get missing declaration:

• Linux Debian
• Arduino 1.8.16
• Teensy Loader 1.55
• Board Teensy40
• USB_TYPE : SERIAL
• https://github.com/PaulStoffregen/LittleFS#main
• Exemple : ListFiles.ino

ERROR: /Applications/arduino-1.8.16/hardware/teensy/avr/libraries/LittleFS/src/LittleFS.h:60:31: error: 'DateTimeFields' has not been declared

Thanks for your help

You need to either update the core library (new versions have DateTimeFields), or install a recent beta which updates everything.
