I draw your attention to these possibly relevant changes to gnuplot
from last year.  These are in the development code but not in the
current version 5.4 release.    Is there interest in having these changes
back-ported to 5.4?

   "set mxtics time <N> <units" 
    
   Allow explicit choice of minitic placement along time axis. 
   For example 
       set mxtics time 1 month 
   places a minitic exactly on the 1st day of Feb/Mar/Apr even 
   though this does not correspond to equal intervals measured in days.
commit 529062ae873901010d138e68897d8f6d057a8e7a

   Revise auto-placement of tics for time data 
    
   For timescales of days or longer, if a ticmark is generated for 
   some date then place it at the start of that same day (0 AM). 
   The spacing between "day" tics is always exactly N days. 
    
   It used to be that the date was rounded up if time > 22:00 but 
   hours/minutes/seconds were left unchanged. This meant that the 
   tic positions were not exactly on a day boundary and might not 
   even be on the same day. Thus the spacing between "dates" was not 
   an integral number of days. 
    
   This discrepancy was particularly obvious when using the new 
   option "set minitics time N days", since the evenly spaced 
   minitics did not align with the major tics.
