> Using simple date format "yyyy-MM-dd-HH-mm", startTime 01-01-2015 will get formatted to 2015-01-01-00-00 on a server / developer machine running with UTC time zone where as the same will be formatted to 2015-01-01-05-30 on a server / developer machine running in IST. 
> A test case which is expecting 2015-01-01-00-00 as a result of formatting will run fine in UTC time zone and will fail when the same is run on a machine in some other time zone. Test case can be made more generic by creating expected formatted string in local time zone but thats just adding un-required complexity to test case. 
> Also changing displayed time strings based on client time zone can be a requirement but changing the same based on the time zone of the machine (server) on which code is run seems to be an undesired behavior.
> One of the ways to fix this is to create SimpleDateFormat instance with time zone as UTC and consistently use UTC everywhere to keep things simple:
> SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-dd-HH");
> sdf.setTimeZone(TimeZone.getTimeZone("UTC"));
