Shuyu Zhang, That error is trying to explain exactly what's happening, but because it's coming out of a parser, it's a little hard to read, so I'll try to translate it for you. It's basically saying I'm using "2006-01-02T15:04:05Z07:00" as a template to parse "2016-012-18T16:00:00Z" and ran in to trouble after I had parse everything except "2-18T16:00:00Z" when I expected the next, left most, character to be a "-" {noformat} 2006-01-02T15:04:05Z07:00 <- expected 2016-012-18T16:00:00Z <- actual        ^        Here, the parser expected a "-" when a "2" was found. {noformat} Ultimately, your problem is just that the date parser won't parse three digit months. Just convert your three digit months to two digit months and you should be ok. Thank you, Gabriel
