            Bug ID: 238626
           Summary: Date parse error with ISO 8601 date+time input,
                    whitespace delimited time (YYYY-MM-DD HH:mm:ss)
           Product: WebKit
           Version: Safari 15
          Hardware: iPhone / iPad
                OS: iOS 15
            Status: NEW
          Severity: Normal
          Priority: P2
         Component: JavaScriptCore
          Assignee: webkit-unassigned at lists.webkit.org
          Reporter: strarsis at gmail.com

On `iOS`/`iPad` Safari browser engine the JavaScript `Date` fails to parse `ISO 8601` date+time inputs where the date and time are delimited by a white-space instead of the `T` character (e.g. `2022-03-22 17:51:57`): 
The `Date` constructor fails with `Invalid date format`.

The usage of a white-space as delimiter between date and time isn't specified by ISO 8601, but is allowed by the RFC that is mostly used on the web.
Most Browsers and JavaScript libraries support and output `ISO 8601` formatted dates with date+time delimited by a white-space (`Chrome` (`Blink`/`Chromium`); `Firefox` (`Gecko`); `FeathersJS`; ...).

Code demonstration: `new Date('2022-03-22 17:51:57')`
