1.6.7 IDE, Generic ESP standalone. I have tried shuffling the functions to cover the strange behaviour introduced from IDE 1.6.6 onwards.
With this RTC example sketch:
/**************************************************************
* Blynk is a platform with iOS and Android apps to control
* Arduino, Raspberry Pi and the likes over the Internet.
* You can easily build graphic interfaces for all your
* projects by simply dragging and dropping widgets.
*
* Downloads, docs, tutorials: http://www.blynk.cc
* Blynk community: http://community.blynk.cc
* Social networks: http://www.fb.com/blynkapp
* http://twitter.com/blynk_app
*
* Blynk library is licensed under MIT license
* This example code is in public domain.
*
**************************************************************
* Blynk can provide your device with time data, like an RTC.
* Please note that the accuracy of this method is up to several seconds.
*
* App dashboard setup:
* RTC widget on V5
*
* WARNING :
* For this example you'll need SimpleTimer library:
* https://github.com/jfturcot/SimpleTimer
*
* And also this Time keeping library:
* https://github.com/PaulStoffregen/Time
*
* This code is based on an example from the Time library:

// Wait until connected
}
// Display digital clock every 10 seconds
timer.setInterval(10000L, clockDisplay);
}
// Digital clock display of the time
void clockDisplay()
{
// You can call hour(), minute(), ... at any time
// Please see Time library examples for details
BLYNK_LOG("Current time: %02d:%02d:%02d %02d %02d %d",
hour(), minute(), second(),
day(), month(), year());

void loop()
{
Blynk.run();
timer.run();
}
I get the following error which indicates Time.h is not being picked up. When I run Time examples that uses TimeLib.h the serial time compiles ok.
