  • Linux Tutorial Series – 163 – Time

    Here is the video version, if you prefer it:

    A quick word on time in Linux – incorrect time can cause web browser issues. (“How to troubleshoot time related errors on secure websites,” n.d.)⁠ Many distributions support using the NTP (Network Time Protocol) daemon to maintain the time using the remote server. (Ward, 2014)⁠ You can also mangle with timezones, but I never needed this. My advice: Don’t mangle with time unless you really need to (such as when you find the error above). I never had to.

    Thank you for reading!

  • Linux Tutorial Series – 15 – Talking about time – date and cal

    Here is the video version, if you prefer it:

    Today, let’s talk about two time-related commands in the shell. They are called date and cal. (Shotts, 2019)⁠

    date gives you the current time:

    mislav@mislavovo-racunalo:~$ date

    Sun 22 Dec 2019 12:11:15 PM CET

    cal gives you the calendar:

    mislav@mislavovo-racunalo:~$ cal

    December 2019

    22 23 24 25 26 27 28

    29 30 31

    Obviously, applications of this are vast. Let’s say you freeze yourself and wake up 70 years in the future. Of course you’re not going to ask some human what year is it! That would be ludicrous! Instead, you will find the first computer with Linux and run the commands you learned from this article. I just saved your life 70 years in the future. You are welcome.
