Clock stuck on lemonbar

[alecive]

Hi @baskerville ,

I am an happy bspwm user, but I am having this issue with the clock applet with lemonbar. What happens is that everything works fine, until at some point the clock is stuck and does not get updated any more.

Everything else (like the battery, xtitle, workspaces etc) works, which means that it should be more of a clock issue rather than a lemonbar issue (this is why I am reporting it here).

Strangely enough, if I type clock from a terminal it prints out the correct time.

FYI below is my panel script (I could have cut off the not important things but I preferred to keep it as-is). I call it in my init.sh as panel.sh &
