Does it have a date created?

[techtoys]

It has a date created but it is always of Tuesday, 1 January 1980 (see screen capture). Is there any API to set the file creation time?

[serfreeman1337]

You need to set system wide clock. Either manualy using settimeofday:

void setup() {
  timeval now;
  now.tv_sec = 1680555600; // 04/04/2023 00:00 UTC
  settimeofday(&now, nullptr);
}

or via NTP.
