Outputting time to screen

FastFullBack

this is what i have so far only it seems to be going very very fast:

current = System.currentTimeMillis();
secs = current%1000;
secs = secs%100;
current = current/1000; //puts it into seconds
mins = current%60;
current = current/60; //puts it into minutes
hours = current%60;
current = current/60; //puts it into hours
current = current/24; //puts it into days
current = current/365; //puts it into years

then i output the hours, mins, and secs , only there the wrong values and when i reload it they have advanced away too much.

When I outputed current it did however give 33 which is right.
Anyone got any tips on synchronizing the time correctly.

If you look at the java API you'll see that System.currentTimeMillis() gives "the difference, measured in milliseconds, between the current time and midnight, January 1, 1970". Given the calculations above, this is more than likely your problem....

Hi,

Your maths are way off. Below would be more what you are looking for...

long current = System.currentTimeMillis();		
// Change to seconds
current /= 1000;
// Find the seconds
long secs = current%60;
// Change to minutes
current /= 60;
// Find the minutes
long mins = current%60;
// Change to hours
current /= 60;
// Find the hours
long hours = current%24;
// Change to years
current /= 24*365; 

Every line after the "change to" comments changes the current value to a different value since 1970.... such as hours since 1970 etc.

However, unless you have a particular reason for doing it in this way ( college project - have to show knowledge of how it works, etc. ), then you should look into the Calendar class.

Thanks found the calender class and got that going.Any ideas on how to keep this time value continously updated?
Thanks

Look up the API on using Threads. Loads of tutorials on them too..
