# Troubleshoot time-related SSL errors on secure websites

Published on June 14th, 2020

As I was configuring Arch Linux setup on my old HP 8460p laptop, I noticed that I wasn't able to access any site using Chrome or Firefox as I was faced with a weird error:

I was quite confused and thought it might be an issue with my WiFi card or probably some server issue but turns out it was neither of them.

On the side of my screen, I noticed my system time was displaying 4 hours ahead of the current local time, which is wrong. So, I did a little research and turns out my suspicions were correct, it's a time-related issue.

## How is time related to secure websites?

Well, each website that uses SSL or that begins with https:// are only valid for a period of time before getting expired. If the website that you're trying to visit presents a certificate with a time and date that doesn't match with your system's clock, Firefox will prevent you from accessing the page.

## How to fix it?

Actually, the fix is quite simple. All you have to is just set the correct date and time on your system and you're good to go!

If you're using Linux, just do the following:

### 1. Set up your timezone

You can look up for your timezones by executing the following:


timedatectl list-timezones | less



Once, you've found your timezone, execute the following by replacing Continent/Country with your timezone:


timedatectl set-timezone Continent/Country



### 2. Manually set your local time

Execute the following to set up your time, locally on your system:


timedatectl set-time "yyyy-MM-dd hh:mm:ss"



### 3. Set the hardware clock from the system clock

The following command sets the hardware clock from the system clock:


hwclock --systohc



Now, that you've executed them, you should be able to view the correct time on your system by executing timedatectl status and you should see something like this:


Local time: Sun 2020-06-14 21:04:04 +04
Universal time: Sun 2020-06-14 17:04:04 UTC
RTC time: Sun 2020-06-14 17:04:05
Time zone: Asia/Dubai (+04, +0400)
System clock synchronized: no
NTP service: inactive



Although, this issue was time-related, you may face the same kind of error for various other reasons. Try reading more on how to troubleshoot errors like these from Mozilla's official documentation.
