How do I stop my Android code from sending Arabic text when sending a date timestamp using the Java Util Date?

Issue

In the app we are trying to send telemetry events to our API but users in Iran are sending through the timestamp formatted as such "۲۰۲۲-۰۷-۰۶T۰۰:۰۳:۳۳.۳۹۰Z".

Exception while executing function:
LogTelemetry Could not convert string to DateTimeOffset: ۲۰۲۲-۰۷-۰۶T۰۰:۰۳:۳۳.۳۹۰Z.
Path 'appTimestamp', line 1, position 54.

The above is the exception the API is returning, the Locale is set to the Default, but I also have not been able to replicate the error by using the Arabic Locale

Below is the method used to get the timestamp

fun getGMTTImeStamp(): String {
    val formatter2 = SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS", Locale.getDefault())
    formatter2.timeZone = TimeZone.getTimeZone("GMT")
    val date = Date()
    return (formatter2.format(date) + "Z")
}

The data is being sent as a Json String. Example below:

{   
    "action":6,
    "appTimestamp":"2022-07-08T08:36:45.454Z",
    "deviceId":"6d0ae55186cd5efc",
    "origin":3,
    "originId":"3c945925-53ac-4fbe-9266-210410903a85",
    "platform":0
}

The only information we have is the error above from the server and that the request was made in Iran

Solution

Setting the Locale to Locale.ENGLISH solved the problem was just difficult to test without setting my device language to Arabic
