Question

Im trying to convert unixtime to date but the results im getting are wrong :
for example i have this unixtime : 1354312800 accurding to this site :
enter link description here
the result is :
Fri, 30 Nov 2012 22:00:00 GMT

but when i do :

long timestamp = 1354312800;
java.util.Date time=new java.util.Date((long)timestamp*1000);
int d = time.getDay();
int m = time.getMonth();

im getting :
d= 6 << this is wrong should be 30.
and m – 11

Answer 1

The method Date.getDay() gives the day of the week (0 = Sunday, …, 6 = Saturday).

Change it to Date.getDate() and you will get 30 as the result.

Some side-notes:

• The Date class is pretty much deprecated. Use Calendar instead, or even better, the Joda time library.

• Your conversion is sort of funny. (long)timestamp*1000 converts timestamp to a long value (which is already a long value) and then automatically widens 1000 to a long value to carry out the multiplication.

  I would skip the conversion, (long) , altogether, and if you want to explicitly say that the factors are long values, use 1000L instead, which is a long-literal.
