What does ${USER:root} mean and how to get its value with Java?

Java Process Linux Command Output Redirection
Following command runs and redirects output to file when I run it on RedHat Linux command line:

I assume it is because of the timezone being TRT instead of EET. This only occurs in one of our linux servers and not on any others which indicates that it is an environmental issue but I couldn’t locate what might be causing it. We are using new Date(System.currentTimeMillis()) to get the date.
