Aligned print spots without seconds

[krasoffski]

In most outputs we specify z as UTC timezone, but for spots we show seconds which in my opinions is meaningless.
Thus, I changed a little output format by removing seconds and z in title as time already contain it.

Hi @krasoffski,
I do agree, seconds are not really useful in the console/debug prompt. Some people use the console to parse the information for specific reporting apps, and changing this format now could have some impacts.

The search window for WSPR is around a couple of seconds, and showing the milli-second could be interesting for some cases, but usually people just want to get the spot.

Thanks for your MR, I will merge it, and I anticipate some impacts, but we will see :)

73, Guenael

@Guenael
Thank you for pointing me about backward compatibility.

But I have to mention that probably in my case I did not see any meaningful seconds for spots.
It was always 00 like bellow for time 06:48:00. That is why I would like to replace 00 to z.
Bat anyway, thank you for your application. :)
