Truncate timestamps

[markbidwell]

Hi Jakob, thank you for making moveVis - it's great!

It seems that align_move() creates dummy timestamps that don't differ in the last position. You can see an example of this on the moveVis home page (https://movevis.org/) where in the first three animations each frame is showing ":59" for the seconds. And in the last animation each frame is showing ":00". In these cases, seconds are not informative because the units were set to minutes, so seconds could be truncated so they are not distracting to the viewer.

In my case, it's the minutes that aren't informative, because I set units hours (one frame per hour), so I would like to truncate the minutes. I have tried to do this using get_frametimes() but haven't been able to figure out how to do it, so I'd appreciate any help.

Thanks in advance, Mark
