That's the way jsplot is working too. In addition the offset is stored in a
common block. Because
if you later on like to use cursor or xcursor you need the offset to show your
data.

May be you want to show at your axes values formated like a human readable
date/time string format instead of axes values between 0 and 86400 (or more)
this will be done by jsplot.

There are a lot of functions behind jsplot to handle date/time strings formats
specially for changing into other formats.
