AWSDateTime doesn't parse ISO 8601 format, is it bug ?

Question

# Summary  
  
"2019-04-09T23:25:27+09:00" is valid ISO 8601 datetime notation certainly.  
"2019-04-09T23:25:27+0900" (colon-less timezone) is also valid I think ( says so, but it is just my conjecture because I don't have ISO 8601 cannonical specification pdf .)  
  
AWSDateTime accepts former, but denied latter.  
I think this is bug because https://docs.aws.amazon.com/appsync/latest/devguide/scalars.html#awsdatetime says:  
  
> The AWSDateTime scalar type represents a valid extended ISO 8601 DateTime string.   
  
# How to reproduce  
  
1. Setup AppSync with Dynamodb backend  
2. Use AWSDateTime as part of GraphQL type  
3. Insert a row with value "2019-04-09T23:25:27+0900" for AWSDateTime in dynamodb console  
4. Query in AppSync console to get the row  
5. Error happens like invalid row value  
  
# P.S.  
  
I haven't checked AWSTime but It may have same problem.

Accepted Answer

Hi,  
  
Thanks for the feedback. At this time, AWS AppSync requires the colon in the timezone. Per our documentation, "...the time zone offset must either be Z (representing the UTC time zone) or be in the format ±hh:mm:ss" (https://docs.aws.amazon.com/appsync/latest/devguide/scalars.html#awsdatetime).   
  
I'll add a task to our backlog to see if we can relax this requirement to support timezones without colons. Unfortunately, I cannot provide an ETA on if/when this can be implemented.
