Example: I take injection every other day and track the location and time of the shot. I have set the default length to 4 minutes. (The time it takes to get everything out, set up, do injection, put medication away.)  If I start at 08:00 AM, the default event time should automatically show as 08:04 AM. Later in the day, my wife and I have a meeting at Noon. I try to record it as 12:00- to end at 13:00, but when I set end time to 13:00, the start time changes itself to 12:56.  Before, I could just delete the event and start over and it would let me set the start/end times I wanted.  Today, it just kept changing them for me.  Until the past few weeks, it always worked properly.  Now, it is driving me nuts. I have been using Lightning or Sunbird since it first was released. Thunderbird & Firefox since it first came out in Beta.

Reproducible: Always

Steps to Reproduce:
1. change default event length from 3 to 4 minutes 
2.
3.
Actual Results:  
set the end time and the start time follows the default event length.

Expected Results:  
Start time should stay as I had set it with only the end time changing. I should be able to set the start time, with the end time changing to the default event length and I should the able to only set the start and then go directly to add my desired comments.

I use the default theme.
