Default date transform does not conform to ISO 8601 standard for dates with timezones

[tomlagier]

This is the default date transform: https://github.com/emberjs/data/blob/master/addon/-private/ext/date.js#L34

Per https://www.w3.org/TR/NOTE-datetime, timezones should be specified as TZD = time zone designator (Z or +hh:mm or -hh:mm)

The regex on the above line only parses Z or +hhmm or -hhmm - note the missing : after the last non-capture group ((?:(\d{2}...).

Looks like a simple mistake, but it breaks out of the box normalization of dates on servers with timezones. Let me know if you would like a PR to fix or if there is some context here that I'm missing. In the meantime, we can create our own normalize function to properly create dates out of those strings.

Hi @tomlagier. We would accept a pr to fix the issue if you have the time.
