Could You please help with if/else code which could display a particular text if uptime is longer than - let's say - 3 days? Otherwise display nothing... I can't figure it out.
The question is where you are going to have the date, but one that you can use is
$if(tf(2019y02M23d)>3,00ffffff,ffffffff)$
Here you are saying that if the days remaining to the 2019 year 02 month 23 day is more than 3, transparent color if not, white color.
Unfortunately I can't see the difference when I set a date which is less than 3 days...
Klwp use seconds to calculate the dates, and if you use days, at the 00:00:01 from today are 0 days to tomorrow(0days 23hours 59minutes). If you want 3 days you can use 4 days, or put the hours too like 23h and put the if = in hours(72) and this I think that are going to work.
