Billions of devices sync with NTP servers daily, checking for and correcting time discrepancies both during boot-up and in the background. NTP is an essential for modern applications and all connected devices

@nixCraft You do realize devices and computers have batteries to save the current time and that a drift of a second or so is not going to impact any of that... right? You act like without NTP, time is going to skew horribly on every single device randomly and unpredictably by hours or days.

And if your device's battery fails, you have bigger issues than just time drift.

NTP time sync is nice in certain situations, but it isn't the life-saving, critical service you make it out to be.

@thespiralcow @nixCraft For https are some minutes into the future already a problem. Different timestamps in the logs is also annoying, if you search for a problem.

It is not the end of the world, but in datacenters you can run into some nasty problems.
