I copied your code above, and it works fine for me.

B4X:

Sub Button1_Click
    Dim pubDate As String' = item.Get("pubDate")
    pubDate="Fri, 24 Dec 2021 20:59:36 GMT"
 
    DateTime.DateFormat = "EEE, dd MMM yyyy HH:mm:ss Z"
    Dim lDate As Long = DateTime.DateParse(pubDate)
    DateTime.DateFormat = "MM/dd/yyyy HH:mm:ss"
    Dim sDate As String = DateTime.Date(lDate)
    Log(sDate)
End Sub

Try to set the locale to US:

B4X:

Dim jo As JavaObject
jo.InitializeStatic("java.util.Locale").RunMethod("setDefault", Array(jo.GetField("US")))

Mahares · Dec 25, 2021

This works:

B4X:

pubDate="Fri, 24 Dec 2021 20:59:36 GMT" 
    DateTime.DateFormat = "EEE, dd MMM yyyy HH:mm:ss Z"   'lower or upper Z
    Dim lDate As Long = DateTime.DateParse(pubDate)
    DateTime.DateFormat = "MM/dd/yyyy HH:mm:ss"
    Dim sDate As String = DateTime.Date(lDate)
    Log(sDate)   '12/24/2021 15:59:36

B4X:

    Dim lDate As Long = DateTime.DateParse(pubDate)

I had similar code but upper Z gave error and worked in lower z.
Try it.

Just to clarify.
The problem is 'Fri' and 'Dec' in the date.
This works only when the device language is set to English.
On my device, the code in post #1 works OK if I replace 'Fri' by 'ven' and 'Dec' by 'déc' because my device language is set to French.
The solution in post #6 was to set the language to English.
