To Reproduce
Steps to reproduce the behavior:

1. Build any example

Expected behavior
Successful build

IDE and its version:

• PlatformIO
• Version 2.2.0

ESP8266 Arduino Core SDK version

• Version 2.5.1

Additional context
If I downgrade to 2.3.0 - no build errors.

I fixed for missing time.h header file. Please update the library.

PlatformIO still see old version 2.3.1 (issue platformio/platformio-api#23).
I tried to apply your commit manually, but the error still here.

[mobizt]

Actually time.h is in the core library. Any third party libraries contained time.h?

Check and search third party lib for time.h, temporary remove it or update platformio again.

The code that you've got the error is just for get NTP server time.
This required for BearSSL/axTLS SSL/TLS handshake process.
If you can't run the below code, the problem may come from time.h include file conflicts.

    configTime(3 * 3600, 0, "pool.ntp.org", "time.nist.gov");
    time_t now = time(nullptr);
    while (now < 8 * 3600 * 2)
    {
        delay(100);
        now = time(nullptr);
    }

    struct tm timeinfo;
    gmtime_r(&now, &timeinfo);

This issue caused by duplicate time.h from other libraries. Please read this and this.

Thank you. The problem was with https://github.com/PaulStoffregen/Time library. It has Time.h.
I renamed it to TimeLib.h and build succeessfuly.
P.S. Arduino IDE does not have this problem with 2.3.1.

I also don't understand why well known dev don't care about naming.
