In Linux Mint I used to place the date/clock on the right hand side of my start panel. In Manjaro I did this too. Now I note a difference in function: in Linux Mint I could right click the date/time, copy and paste the current date/time to a file.
In Manjaro?
Mint has many flavours
just as Manjaro
Mint’s “flagship” is Cinnamon.
Which Manjaro DE are you talking about? - the standard (flagship) is Xfce
in a terminal, type:
date
maybe that helps you - it surely can be copy/pasted
I have got Mint Mate and Manjaro XFCE. A terminal command is certainly possible, however, I need to type date +"%a %Y-%m-%d %H:%M" to obtain the format I like, e.g. Mi 2021-04-07 08:11. The Mint Mate functionality with right click on the clock, copy, paste was more comfortable. Therefore my question.
or you can create an alias 
These are obviously not the same DE and Xfce doesn’t have that functionality which Mate has, apparently.
It’s not a difference between Mint and Manjaro, it’s a difference between the two Desktop Environments.
I have never used Mate, I don’t know it first hand.
Understood. Thanx.
