The values of datenum and timenum refer to the bar values, so you must
write the code to allow for the bar in which the time you want resides
eg
I also changed the time to 10:09:00 am, 1009 refers to 10 minutes
9seconds after midnight
index = ValueWhen(DateNum()==1070829 AND TimeNum()>=100900 and
ref(TimeNum(),-1)<100900, BarIndex());
a fuller set of conditions to allow for checking the first bar time of
the day is
index = ValueWhen(
( DateNum()==1070829 AND TimeNum()>=100900 and ref(TimeNum(),-1)<100900 ) or
( DateNum()==1070829 and ref(DateNum(),-1)<1070829 AND TimeNum()>=100900 ),
BarIndex());
