How to get the current date and time of your timezone in Java?

I have developed a Attendance System and in use for India. Our servers are in US and since they are using PDT. My code reflects time one hour ahead.

say its 9:00 am IST ---- I get the time as 10:00 am IST

other than detecting one hour from the time, which will be a temporary solution.

Pls suggest me some way to overcome this situation

It's not *at all* clear what you're doing here, partly because you haven't shown any code at all. Please give a short but complete example which demonstrates the problem, and read http://tinyurl.com/so-hints — Jon Skeet, Jan 25 '12 at 10:38

To check if a given Date is affected by daylight saving, use

Calendar c = Calendar.getInstance(timezone); // omit timezone for default tz
c.setTime(date); // your date; omit this line for current date
int offset = c.get(Calendar.DST_OFFSET);

0 means no DST, any other value (most likely 3600000) means that this date is affected by DST
