AIJ plots in various forms of JD time (preferably BJD_TDB). The "default" time markers in your plot are just the values that were set last time.  You'll need to convert your UT times to BJD_UTC and enter them in (left, v.marker1) and (right, v.marker2).  You should go through Dennis Conti's guide  from his website to learn how to use AIJ, or better yet, take his AAVSO course that teaches how to use AIJ in zoom sessions if you are lucky enough to get a spot in an upcoming course.
UTC can be converted to BJD_TDB using the CC module (protractor icon on the toolbar), on on various websites. Or the NASA Exoplanet Archive may also give ingress and egress in BJD_TDB.
