1) Using the Applications menu, open a terminal window

2) Set the date and time you want, using the following example as a guide:

sudo date -s "2024-02-20 03:25:55 PM PDT"

  You may need to enter the sudo password (which is the same as the password for the standard "geometrics" user.

3) To change the timezone, use the terminal window to get a list of timezones:

ls /usr/share/zoneinfo

// To drill into a region, expand the command as follows:

ls /usr/share/zoneinfo/Pacific

Set the local timezone using this command:

// Open the timezone file to edit it.  You may need to enter your user password
sudo mousepad /etc/timezone

// Type in the timezone name, of the timezone you want to use, on a single line in the file, for example like this:
Pacific/Guam

 If you want to see your time in UTC, set the timezone to "Etc/UTC".  If you want to set the time in UTC, then when you set the time using the "date" command, use UTC as follows:

sudo date -s "2024-02-20 03:25:55 PM UTC"

1) If you want to type easily, plug a keyboard into the USB socket in the side of the toughpad.  Otherwise, use the screen keypad.

2) Open a terminal window (using the Applications menu).

sudo bash -c "echo 892 > /sys/class/backlight/intel_backlight/brightness"

You will need to enter a password, which is the default password for the standard user. To set different levels, replace the number 892 with other numbers.  892 is the maximum number allowed; lower numbers will result in a dimmer screen.

The change should take place immediately.

Then close the terminal window and return to normal use.
