I wrote a program that must add to some log entry (of some event) a note if event happened just before some other major event or along with it. And i cannot select a good word for this.
This word marks entries for closed browser windows if they closed just before (several seconds) or along with the complete browser close. But it must be a word or a short phrase.
Window X closed ______ Chrome Exit
Window Y closed ______ Chrome Exit
Window Z closed ______ Chrome Exit
I cannot use any of on/during/upon/before/ahead/along/by the time/onward/onwards/preceding/ahead/along/near/fore as the window might be closed just before, simultaneously with Chrome exit.
Upon looks very good, but as I understand it is for the moment just after the major event. Before cannot be used as it includes too long a timeframe. On feels for me like it does not include the time just before the exit.
I need a word or phrase for "just before or in time of".
