Cannot import data into ThingSpeak due to missing timestamp

I've been trying to upload some data into ThingSpeak but it keeps on showing different error each time. First was due to unspported format which I fixed, and then it shows duplicate timestamp and now missing timestamp. I had some issue with formatting time into ISO8601 format but did it. Just don't know what's wrong. Attached is the CSV.file i'm trying to import.

There are 8 fields available for measurements. Your file has 13. You can also have elevation, status, longitude, and lattitude, but the last two are validated to have the correct format for these measurements.

If you click the data import tab, there is a csv template available, and there is more informatio at the channel import page in the documentation.
