Converting milliseconds to hh:mm:ss

[J G]

So I'm building a bigger app that requires the use of a periodic timer that has to be displayed to the user. I have been able to get my desired times to spit out in milliseconds, but unable to display them nicely in an hh:mm:ss second format with leading zeroes. Is there an elegant way to do this or must I code an entire sequence (i.e. convert milliseconds to seconds, display seconds with leading zeroes using segment, when seconds = 60, add 1 to minute and reduce seconds to 0)? If so, how do I reference this entire procedure without having to re-make it multiple times (because there will be a few different timers within the program).

use a procedure with result http://appinventor.mit.edu/explore/ai2/support/blocks/procedures.html#return

input parameter is your time in milliseconds

output is your  time in an hh:mm:ss second format with leading zeroes.

and inside the procedure put your logic

Okay, that much makes sense. I'm having difficulty now with working the procedure. What I am trying to do below is:

1) Take the value of TotalTimeElapsed and spit it into the procedure "Calculate Seconds." That procedure for now will format the seconds between 0 and 60 (obviously later I have to add minutes and hours later). Then that calculation is spit out and displayed in TotalTimeDisp.

Calling the procedure, however, doesn't do anything. It's just spitting out the same as TotalTimeElapsed (i.e. making no changes).

What am I doing wrong?

your blocks look strange...

I recommend you to take a look here to get an idea hwo to work with the clock https://sites.google.com/site/blocks123/theclock

this is AI1, but the blocks are the same in AI2
