I'm wondering if anyone has run across this behavior or if I am somehow doing something wrong. If I try to format a date with TalendDate.dateFormat("YYYY-MM-dd HH:mm:ss", myDate), everything seems to work fine UNLESS the HH is 12 in which case the output is 00:mm:ss.
I am running Talend Studio 7.3.1 with patch R2023-01. The code I used for the testing (all in a tJava component) is:
String dateStr;
String yearToSecFmt = "YYYYMMddHHmmss";
String yearToSecTimeFmt = "YYYY-MM-dd HH:mm:ss";
Date theDate;
Integer timeBase = 2023013000;
Integer currTime;
System.out.println("======================================================================================================");
System.out.println("*****************************************");
for (int h = 0; h < 24 ; h++)
{
currTime = timeBase + h;
dateStr = currTime.toString() + "0346";
theDate = TalendDate.TO_DATE(dateStr, yearToSecFmt);
System.out.println("Hour = " + Integer.toString(h));
System.out.println("Original = " + dateStr);
System.out.println("My Time = " + TalendDate.formatDate(yearToSecTimeFmt, theDate));
System.out.println("*****************************************");
}
The output from this is (note the hour = 12 output has 00 for the hour, not 12, but hour = 13 has 13 for the hour and not 01):

Does anyone know if this is a bug in Talend/TalendDate or what I'm doing wrong, if this is not a bug.
EDIT: This came up in a process where I'm loading data into a database and I'm converting the date time to a DB-compliant format. As this is a somewhat urgent issue for me, I'm going to rework the process to have the DB convert the date string to a DB compliant version but I would like to understand what, if anything, I'm doing wrong.
