Question

Got a strange weirdness when using Dates and Calendar. Point is I want to create a specific date e.g.

Calendar cal = Calendar.getInstance();
cal.set(1970, 0, 1, 0, 0, 0);
Date date = cal.getTime(); 

Now the thing is: it shows the correct date, but when debugging I see under the date-variable a “fasttime” of e.g. -3599459. This makes my JUnit tests fail, because the expected value is -3600000.
It seems the Calendar adds 541 milliseconds or something like when initializing…

Question is: is it not possible to simply create a fixed date without this ‘i’m adding some milliseconds in the background’-ghost function?

Answer 1

Add this line before calling cal.getTime():

cal.set(Calendar.MILLISECOND, 0);

This will make sure you set the milliseconds to zero.
