Talend date and time combine

Question

I combine two columns; date and time. When I pass the date and time hot coded it works fine but when I pass it through a column it throws the error:

Unparseable date: "05/05/1992"

I already tried this:

MaterialCodeCSV.xdate == null ? 
TalendDate.parseDate("yyyy-MM-dd HH:mm:ss", TalendDate.getDate("yyyy-MM-dd HH:mm:ss")) : 
TalendDate.parseDateLocale("yyyy/mm/dd HH:mm:ss",MaterialCodeCSV.xdate.toString() +  MaterialCodeCSV.xtime.toString(),"EN"); 

Java code in Talend:

Date handling can be a bit tricky if using wrong data types. I assume you want to fill a field which is a Date. There are several errors with this way:

MaterialCodeCSV.xdate == null ? 
TalendDate.parseDate("yyyy-MM-dd HH:mm:ss", TalendDate.getDate("yyyy-MM-dd HH:mm:ss")) : 
TalendDate.parseDateLocale("yyyy/mm/dd H:mm:ss",MaterialCodeCSV.xdate.toString()+ MaterialCodeCSV.xtime.toString(),"EN");

• If MaterialCodeCSV.xdate == null you create a date and parse it again instantly? That seems unneccessary complex and inefficient. Change this to TalendDate.getCurrentDate()
• Then if xdate is not null, you just concat xdate and xtime, use toString() and try to parse this. Again, this seems unneccesary complex. If I just assume now and xdate and xtime are already Date fields, you could write it as this: MaterialCodeCSV.xdate + MaterialCodeCSV.xtime.
• If both are String fields, you have to make sure that xdate is formatted yyyy/MM/dd and xtime is HH:mm:ss. Then you could exclude .toString()
• Also, if both are String fields, you have to add an additional space: MaterialCodeCSV.xdate + ' ' + MaterialCodeCSV.xtime
• Additionally, in the first case you parse with yyyy-MM-dd HH:mm:ss. In the second case you parse with yyyy/mm/dd H:mm:ss. This reads "year/minute/day". Also there is only one hour digit, not allowing anything after 9:59:59 o'clock to be parsed. Correctly you should use yyyy/MM/dd HH:mm:ss.

So to conclude it should look like this (if I assume correctly and you are using correctly formatted String fields for xdate and xtime):

MaterialCodeCSV.xdate == null ? 
TalendDate.getCurrentDate() : 
TalendDate.parseDateLocale("yyyy/MM/dd HH:mm:ss", MaterialCodeCSV.xdate + ' ' + MaterialCodeCSV.xtime,"EN");
