5 minutes cron not working

[renejanssen1]

hi i have an Wemos d1 mini v.3.00
I've made a cron to run every 5 minutes.
So i expected output times like
9:45:00
9:50:00
9:55:00
but i get
10:46:44
10:51:44
10:56:45

#include <time.h>                       // time() ctime()
#ifdef ESP8266
#include <sys/time.h>                   // struct timeval
#endif
#include "CronAlarms.h"
void setup() {
  Serial.begin(115200);
  while (!Serial) ; // wait for Arduino Serial Monitor
  Serial.println("Starting setup...");
  Cron.create("0 */5 * * * *", Repeats, false);
  Serial.println("Ending setup...");
}
void loop() {
  delay(1000);// do other things... like waiting one second between clock display
}

void Repeats() {
    postData();
}

postData() is sending something to my server.
Thanks already René

Already solved, it needs a ntp server to get the correct current time.
