B4J Question Datetime to Timestamp

[darabon]

I have a UTC datetime as follows:
2021-01-17 10:42:28

How do I can convert this datetime to my timezone?
I try to parse it with DateTimeParse and set timezone to my needing timezone and then get time.
But it's wrong
Please help me

Best way is to add the timezone to the string:

Sub AppStart (Args() As String)
    Dim t As Long = DateToTicks("2021-01-17 10:42:28")
    Log($"$DateTime{t}"$)
End Sub

Sub DateToTicks (s As String) As Long
    Dim t As String = DateTime.DateFormat
    DateTime.DateFormat = "yyyy-MM-dd HH:mm:ss Z"
    Dim res As Long = DateTime.DateParse(s & " +0000")
    DateTime.DateFormat = t
    Return res
End Sub

Thank you but your code have a problem
We have to set timezone to 0 (UTC)
and then DateTimeParse and again set timezone to us country and again get time
In this case, We get local time according to UTC time
Isn't it Erel?

No. Run my code. It works correctly.

You will see the local time in the logs.
