M5unified corrupt ntp time

[kbencherki6-beep]

Hi,
I'm using m5unified in my code and I'm synchronizing time with NTP, but the call to m5.begin() corrupts time. I need m5unified for the power management that I also use.
Here is my code :

`#include <WiFi.h>
#include "time.h"
#include "LittleFS.h"
#include "M5UnitENV.h"
#include <M5Unified.h>
#include <M5GFX.h>

M5GFX display;
M5Canvas canvas(&display);

SHT3X sht30;

RTC_DATA_ATTR int bootCount = 1;

const char* ssid = "";
const char* password = "";

int timeS = 0;

void setup() {
// put your setup code here, to run once:
Serial.begin(115200);
M5.begin();
M5.Power.begin();
display.begin();
sht30.begin();
LittleFS.begin();

display.setEpdMode(epd_fast);

WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
}

configTzTime("WEST0WEST,M3.5.0/1,M10.5.0", "pool.ntp.org");

canvas.createSprite(540, 960);
canvas.setFreeFont(&Orbitron_Light_24);
canvas.fillScreen(WHITE);
canvas.setTextColor(BLACK, WHITE);
canvas.setTextSize(2);

printTimeDate();
printBatteryLevel();
printMeasurements();
canvas.drawPngFile(LittleFS, "/images/m5stack.png", 70, (canvas.height() - canvas.fontHeight() - 20 - 133), 400, 133);
canvas.pushSprite(0, 0);

bootCount++;

delay(5000);

WiFi.disconnect(true);
WiFi.mode(WIFI_OFF);

canvas.fillScreen(BLACK);
display.clear();

esp_sleep_enable_ext0_wakeup(GPIO_NUM_38, LOW);
esp_deep_sleep_start();

}

void loop() {
// put your main code here, to run repeatedly:
}

void printTimeDate(){
struct tm timeinfo;
if(!getLocalTime(&timeinfo)){
Serial.println("Failed to obtain time");
return;
}

char hour[7];
char date[7];
char year[5];  
strftime(hour, 7, "%H:%M", &timeinfo);
Serial.println(hour);
strftime(date, 7, "%d/%m", &timeinfo);
Serial.println(date);
strftime(year, 5, "%Y", &timeinfo);
Serial.println(year);

canvas.fillRect(10, 20, canvas.textWidth(hour), canvas.fontHeight(), WHITE);
canvas.drawString(hour, 10, 20);
canvas.drawLine(0, (canvas.fontHeight() + 20), canvas.width(), (canvas.fontHeight() + 20), BLACK);
canvas.drawLine(0, (canvas.height() - canvas.fontHeight() - 20 - 10), canvas.width(), (canvas.height() - canvas.fontHeight() - 20 -10), BLACK);
canvas.fillRect(10, (canvas.height() - canvas.fontHeight() - 20), canvas.textWidth(date), canvas.fontHeight(), WHITE);
canvas.drawString(date, 10, (canvas.height() - canvas.fontHeight() - 20));
canvas.fillRect((canvas.width() - canvas.textWidth(year) - 10), (canvas.height() - canvas.fontHeight() - 20), canvas.textWidth(year), canvas.fontHeight(), WHITE);
canvas.drawString(year, (canvas.width() - canvas.textWidth(year) - 10), (canvas.height() - canvas.fontHeight() - 20));
}

void printBatteryLevel() {
int32_t batteryLevel = M5.Power.getBatteryLevel();
canvas.setCursor((canvas.width() - canvas.textWidth(String(batteryLevel)) - canvas.textWidth("%") - 10), 20);
canvas.printf("%03d%%", batteryLevel);
}

void printMeasurements() {
if(sht30.update()) {
int temperature = String(sht30.cTemp).toInt();
int humidity = String(sht30.humidity).toInt();
char buffer1[10], buffer2[10];
sprintf(buffer1, "%d", temperature);
sprintf(buffer2, "%d", humidity);
const char* temp = buffer1;
const char* hum = buffer2;

canvas.setTextSize(3);
canvas.drawRect(((canvas.width() / 2) - 200), ((canvas.height() / 2) - 200 - 50), 400, 200, BLACK);
canvas.drawPngFile(LittleFS, "/images/thermometer.png", ((canvas.width() / 2) - 200 + 100), ((canvas.height() / 2) - 200 - 50 + 50), 100, 100);
canvas.drawString(String(temperature), ((canvas.width() / 2) - 200 + 400 - canvas.textWidth(String(temperature)) - 80), ((canvas.height() / 2) - 200 - 50 + 100 - (canvas.fontHeight() / 2)));
canvas.drawRect(((canvas.width() / 2) - 200), ((canvas.height() / 2) + 50), 400, 200, BLACK);
canvas.drawPngFile(LittleFS, "/images/humidity.png", ((canvas.width() / 2) - 200 + 100), ((canvas.height() / 2) + 50 + 50), 100, 100);
canvas.drawString(String(humidity), ((canvas.width() / 2) - 200 + 400 - canvas.textWidth(String(humidity)) - 80), ((canvas.height() / 2) + 50 + 100 - (canvas.fontHeight() / 2)));  

}

Could you please answer me? I don't know what to do to solve this problem.
