Notes about time in UNIX and Linux systems (II): NTP

The second part of this post about time management I will write about the NTP and its daemon configuration. As I mentioned in the previous post, if you need a very accurate time the best option is using the implementation of the protocol. If you need security over accuracy, then you can use OpenBSD project implementation. OpenNTPd is not a complete implementation of the protocol, but as usual in the OpenBSD software, it’s a good, well-documented, audited code.

Notes about time in UNIX and Linux systems (I): time zones

I decided to write about handling the time at UNIX/Linux systems because a message like this: [29071122.262612] Clock: inserting leap second 23:59:60 UTC I have similar logs in my servers last June 30, 2015. Of course, I was aware about it some months before and I have to do some work to be ready (kernel/ntpd upgrades depending on the version of the package, we work with 8 main releases of 3 GNU/Linux distributions).

Old habits, new times

Today I begin a new blog. This will be my third project. More than 12 years ago three friends began Juanjo, Cañete and me wrote about technology, the University where we were studying, politics… That was the age when people socialised at blog level, you could trace a social network following the links in the blogs to other blogs. Most of them were written in free services like Blogspot, Photoblog… People left behind the unconfortable, ugly, poorly updated static pages of the 90’s, and new hobbyists and experts in different areas (but with no idea on web developing) began to write and enrich the Wide World Web.
