The macro defined namespaces confused the hell out of lupdate and more or less broke translations permanently. Looks like the only way we can do it is to have a hardcoded namespace, which goes against my instinct, but honestly how likely is it that we'll change the namespace anyway (I guess forks might want to do it, but that's their problem ;) )

* `time` - time in seconds presented in a rational form
|
|
* `timebase` - the base time unit of an audio/video stream in seconds
|
|
* `timestamp` - an integer representation of a time in timebase units (in many cases is used like a frame number)
|
|
* `timecode` a user-friendly string representation of a time according to Timecode::Display
