If you use date as values for item starttime and item endtime, then OnItemMove will give you NaN as result for the new start time.
If you pass unix timestamps then things work.
I ran into a similar issue.
Solved with using unix timestamps in milliseconds for starttime and endttime
I feel like this timeline should only support unix timestamps in ms as the input. marshaling between strings, Date object, Moment and milliseconds is a pain.
Simplify, simplify and simplify!
Fully agree.
Fix should go out in next release
Fixed in 0.17.0
