Dim ulid As String = "01GRH14AA82EY9A7S99YYF2QDY"

Dim dt As New Chilkat.CkDateTime

' Unix timestamps stored in ULIDs should be UTC...
Dim bLocal As Boolean = False
' Set the CkDateTime from the timestamp contained in the ULID
Dim success As Boolean = dt.SetFromUlid(bLocal,ulid)
If (success = False) Then
    Debug.WriteLine("ULID was not valid.")
    Exit Sub
End If


' You can now get the date/time in any desired format.
' For example:
Debug.WriteLine("Unix timestamp = " & dt.GetAsUnixTime(bLocal))
Debug.WriteLine("RFC822 = " & dt.GetAsRfc822(bLocal))
Debug.WriteLine("Timestamp = " & dt.GetAsTimestamp(bLocal))

' Sample output:

' Unix timestamp = 1675608861
' RFC822 = Sun, 05 Feb 2023 14:54:21 GMT
' Timestamp = 2023-02-05T14:54:21Z
