When using time data on the X axis, the major tics are rounded to start-of-month dates, even if the tics interval was specified as some round number of days. How do I force the tics to be placed at the specified interval?

set mxtics nweeks

Note that the major tics should be exactly 6 weeks apart, but are being placed instead at (some) start-of-month days. The minor tics following each major tic are 7 days apart, as they they should, but start againg at every major tic and etend beyond the next major tic, so that they end up irregularly spaced too.
