Tab5: Arduino configTime and configTzTime return the wrong date and time (way off)

dheijl

The configTime() or configTzTime() functions do not return errors but the returned date and time are way off: up to 2 days in the future and totally wrong time too.

The esp32 code shown in this makernote works without fail on the same Tab5 device.

my platformio.ini:

[env:esp32p4_pioarduino]
platform = https://github.com/pioarduino/platform-espressif32.git#54.03.21
upload_speed = 1500000
monitor_speed = 115200
build_type = debug
framework = arduino
board = esp32-p4-evboard
board_build.mcu = esp32p4
board_build.flash_mode = qio
board_build.partitions = default_16MB.csv
board_build.filesystem = spiffs
build_flags = 
	-DBOARD_HAS_PSRAM
	-DCORE_DEBUG_LEVEL=5
	-DARDUINO_USB_CDC_ON_BOOT=1
	-DARDUINO_USB_MODE=1
lib_deps = 
	https://github.com/M5Stack/M5Unified.git
	https://github.com/M5Stack/M5GFX.git

Other Arduino stuff is broken too: after wakeup from lightsleep the display does not work properly half of the time: the cursor position is sometimes totally off, or sometimes it does not wake at all. I suppose the display needs a hardware reset via a GPIO, but can't find any mention of this in the docs.

But the hardware is very nice indeed. Especially the undocumented coin battery backup for the RTC is a nice surprise!
