The way to update text

data examples:
{“time”:“11:00:00”, “a”:“cesium”},
{“time”:“11:00:30”, “a”:“cesium”},
{“time”:“11:01:00”, “a”:“community”},

i want to update text with time, like using “sampledProperty(time, data)”
i know it doesnt work at this case.

someone says “timeintervalcollection” can help, however i never catch the points…
how can i use “timeintervalcollection” to update text?

finally i got the points, maybe
i used ‘for loop’ but it didnt work
so, changing this using ‘time’
