I want to include my timezone in datetime stamps in dialogs, but the variable values are blank (or missing) in Dolphin and Kalarm.

I set an environment variable TIMEZONE in ~/.kde/env/path.sh (or ~/.config/plasma-workspace/env/path.sh) as
export TIMEZONE=$(date +%Z)
which resolves to MST (Mountain Standard Time) and in /etc/environment
export TIMESZONE=MDT
(Mountain Daylight Time-hard coded purposely as Daylight since substitutions are forbidden).

When I run a routine in Cron the timezone displays correctly as 2020-11-29 15:42:46 MDT.

In a terminal session attached to Dolphin if I echo $TIMEZONE I get a blank line instead of MST. Same is true in Kalarm scripts. I get a blank.
When I enter
printenv>printenv.txt
and edit printenv.txt TIMEZONE shows as TIMEZONE=blank.
Same thing happens if I issue the same command as a script from Kalarm.

echo $TIMEZONE in Konsole properly shows MST:

Code: Select all

2020-11-29 16:04:06 MST rob@sigma:~$ echo $TIMEZONE
MST
2020-11-29 16:04:14 MST rob@sigma:~$

To further confuse things since $TZ is not created in KDE Neon I created it as

Code: Select all

# TZ will be the time zone spelled out in full, e.g. for MST it would be 'America/Boise'. : Updated 2020-11-27 @ 15:53:44 MST by rob@sigma
TZ=$(cat /etc/timezone)  # TZ is not always initialized as an environment variable in all linux distributions so do it here.
export TZ=$TZ


in the path.sh script and

export TZ=America/Boise
in /etc/environment. TZ shows as America/Boise in Konsole, Dolphin, and Kalarm when using printenv.

Running the following Cron job
27 16 * * * root printenv > /tmp/env.txt
yields /tmp/env.txt:

Code: Select all

DESKTOP_ENVIRONMENT=kde
IN_CRON=This environmental variable was created in /etc/environment by rob (01:17:08 02/06/13) and should appear in the cron environment (kilroy was here).

Can someone tell me how environment variables are created or made available to Kalarm and Dolphin? I am confused and need some help.

I

I learned that autostarting kalarm does not load the correct path nor the entire set of environment variables, but if I run kalarm from konsole the correct path and all environment variables are present. That leads me to believe the issue lies with autostart. I will try removing kalarm from autostart and running a startup script that is delayed 15 seconds to see if that fixes the problem.

Any help/comments would be appreciated.
