** Description changed:

  In an attempt to reduce unnecessary frequent periodic file access to
  save power, I noticed that indicator-datetime-service is opening and
  closing /etc/localtime every 5 seconds on my desktop and not apparently
  reading this file.   On the ubuntu phone it is doing the same thing with
  /etc/writable/localtime.
  
  This seems a little excessive, especially because the TZ data doesn't
  change quite that frequently.  It would be useful if this excessive
  polling on the file could be reduced if possible.
+ 
+ [Impact]
+  * Battery drain, wasting energy by a lot of unnecessary polling
+ 
+ [Test Case]
+  * Observe how often /etc/localtime or /etc/writable/localtime gets opened for reading
+ 
+ [Regression Potential]
+  * Possibility to not get the local time reliably
