I have a Java app that runs on a server present in USA. My app has a method which finds difference between local time and another timestamp value which is fetched from the database and I need to check whether this difference is greater than 86400 seconds(1 day). My problem here is, the server is following GMT, I am unable to find the local time in milliseconds. I tried to find the offset between USA time and GMT Time and then subtract from the System.currentTimeMillis() to find the local time in USA, with the help of following code 

int Offset_inmillis = Calendar.getInstance().getTimeZone().getRawOffset();
int DSTSavings_inmillis = Calendar.getInstance().getTimeZone().getDSTSavings();
long localtime_inmillis = System.currentTimeMillis() + DSTSavings_inmillis + Offset_inmillis;

But since the server is taking GMT into consideration, the above code is again giving the GMT time value in milliseconds(Both Offset_inmillis, DSTSavings_inmillis values are 0 in the code above). I can provide a work around by subtracting the offset(hardcoding the offset value in the code), but I dont want to do that since, it doesnt take care of daylight savings and the code doesnt work if its hoisted on a different server in a different timezone.

I need solution where the code works for all timezones. For that, I need the solution to find the local time (in milliseconds) of the server(but server is following GMT time in this case). Can anyone help?

    To find the difference between local time and another timestamp value which is fetched from the database 

    // Change 'America/New_York' depending on the local timezone of your server
TimeZone tz = TimeZone.getTimeZone("America/New_York"); 
// Gives the offset of your server timezone from the GMT
long tzoffset = tz.getOffset(Calendar.getInstance().getTimeInMillis());

    btw, ideally database timestamp should be in GMT as well
