Bug Description

I'm using the "daily build" of gpredict on Ubuntu 14.04.

When selecting a time on the Time Controller, Gpredict jumps to a time one hour ahead of the entered time. This is only visibile when I press "play forward" and the time jumps one hour ahead (the satellites don't change position because they were already set to the hour ahead).

Hi Kyle,

I'm not sure I understand the problem you experience. Could you provide step by step instructions for how to reproduce it?

Here is how it supposed to work:
When the forward or backward button is pressed the time is updated automatically and will override any new value entered manually. If you press the middle button the time updates will stop and you can select a time manually.

The steps I just took to recreate the problem:
- Gpredict is open in Polar/SingleSat View
> Open Time Controller
> Pause Time
> Select a previous day (I don't think this bug works same-day), in my case 30 Oct 2014
> Manually Type in a time (Must be typed, I don't think this bug affects the scroll buttons)
> Hour: 10
> Min: 48
> Sec: 39
- Unisat-6 and Eagle-2 are visible, my single sat is set to Vermont Lunar which is at -2 deg el
> Press play
- Time immediately jumps to Hour:11, but everything else stays, satellites move forward normally from where they, meaning they were already at the hour ahead of what I typed in

Is there a better way to display screenshots?

It certainly sounds like an error.

Just to add a note, I just ran a few tests:

- Dates in September: Failed to replicate
- Dates in October: Problem was observed
- Dates in November: Failed to replicate

So it might be October specific.
