+### -DateKind
+
+Specifies the method used when parsing date time values in the JSON string. The acceptable values for this parameter are:
+
+- `Default`
+- `Local`
+- `Utc`
+- `Offset`
+- `String`
+
+`Default` will convert the value as a `[datetime]` instance with a `Kind` property set as follows:
+
+- `Unspecified`, if there is no time zone information in the input string.
+- `Utc`, if the time zone information is a trailing `Z`.
+- `Local`, if the time zone information is given as a trailing UTC _offset_ like `+02:00`. The
+  offset is properly converted to the caller's configured time zone. The default output formatting
+  doesn't indicate the original time zone offset.
+
+`Local` will convert the value as a `[datetime]` instance with a `Kind` property set as `Local`. If a timezone offset was in the converted string the **DateTime** value will be converted to the equivalent local time.
+
+`Utc` will convert the value as a `[datetime]` instance with a `Kind` property set as `Utc`.
+
+`Offset` will convert the value as a `[DateTimeOffset]` instance with the timezone offset of the original string preserved in that instance. If the raw string did not contain a timezone offset, the **DateTimeOffset** value will be specified in the local timezone.
+
+`String` will preserve the value as a `[string]` instance. This ensures the value is round-trippable and any custom parsing logic not exposed by the other `-DateKind` options can be applied to the raw string value.
+
+This parameter was introduced in PowerShell 7.5.
