The problem is, when i try to convert it to different format using this code: CDate("12/02/21 10:56:09").ToString("MMM. dd, yyyy HH:mm:ss") It displays Dec. 12, 2021 10:56:09 . How can i correctly format it to: Feb. 21, 2012 10:56:09 ? This format is returned when i check balance inquiry fro my SMS based application.

I would really appreciate some help creating some JavaScript that will eventually be used in Selenium that automatically sets a date 10 days ahead from the current date and displays in the following format dd/mm/yyyy. I currently have the script below, but I'm not getting anywhere with it : var myDate=new Date(); myDate.now.format(myDate.setDate(myDate.getDate()+5),("dd/mm/yyyy"); Any help would be much appreciated.

I've been struggling for a while with this piece of code for an Android app and I can't get the hang of it.
