Question

I have a simple gnuplot command file:

 ....
set xdata time
set timefmt "%s"
set format x "%H:%M"
....

where x – timestamp column.

Result – time in UTC format. Can I change local timezome for x axis ?

Answer 1

Just came across this in the docs today:

The conversion to and from seconds assumes Universal Time (which is the same
as Greenwich Standard Time). There is no provision for changing the time
zone or for daylight savings. If all your data refer to the same time zone
(and are all either daylight or standard) you don’t need to worry about these
things. But if the absolute time is crucial for your application, you’ll
need to convert to UT yourself.
