- How can I get the current date and time in UTC or GMT in Java? 28 answers
I am trying to get current UTC date time in millis. But every code I used for this returns me the device's current date time. When I chenge my device's date, time it shows me chenged one. So, I want to get GMT/UTC date time so that it will show me correct date even if user changes the date, time of his/her device.
Codes I tried:
Calendar calendar = Calendar.getInstance(); long now = calendar.getTimeInMillis();
DateFormat df = DateFormat.getTimeInstance(); df.setTimeZone(TimeZone.getTimeZone("UTC")); String gmtTime = df.format(new Date()); Date gmtDate = df.parse(gmtTime);
Actually I want to set an alarm at November 15 2017, 5 PM using AlarmManager, receive that event hide some activities in my app which I don't want to show after this date, time.
How can I acheive this?
Thanks in advance!
