NTP-TZ-DST.ino example is not working (ESP8266 platform)

Why standard NTP-TZ-DST.ino example is not working correctly, returning January, 1, 1970?
NTP0_OR_LOCAL1 defined as 0, wifi is connected ok, internet connection is also ok.

output sample:
---8<---
clock:5/652032000ns millis:5652 micros:5652044 gtod:5/614778us time:28804 ctime:(UTC+120mn)Thu Jan 1 08:00:04 1970

p.s. example from here: link is working.

Seems like I've found the problem, see below.
Here how it was in original code (in setup() ):

#else // ntp

  configTime(TZ_SEC, DST_SEC, "pool.ntp.org");
  WiFi.mode(WIFI_STA);
  WiFi.begin(SSID, SSIDPWD);
  // don't wait, observe time changing when ntp timestamp is received

#endif // ntp

Here the problem is solved:

#else // ntp

  //configTime(TZ_SEC, DST_SEC, "pool.ntp.org"); //WRONG! Call it after wifi connection
  WiFi.mode(WIFI_STA);
  WiFi.begin(SSID, SSIDPWD);
  // don't wait, observe time changing when ntp timestamp is received - WRONG! 

  //Wait for connection.
  while (WiFi.status() != WL_CONNECTED) 
    {
    delay(500);
    Serial.print(".");
    }
    configTime(TZ_SEC, DST_SEC, "pool.ntp.org");

#endif // ntp
