I\'m trying to consolidate some code that is very messy but I want to make sure I don\'t break things. In some places I see a date created as Calendar.getInstance().getTi
In theory, no, because both java.util.Date and java.util.Calendar.getInstance() eventually use System.currentTimeMillis() to return the current time.
The Calendar implementation, however, takes other things into consideration, like the Locale, or if the locale is JP or TH... you can see that in the source code of both classes.
