For many formats, it is not possible to have a precise "jump to position" because the bitrate is not constant or the seektable is not granular enough. In addition, the time reported by LMS on the UI is not perfect. It is the estimation that LMS does, added to the playback time reported by the player. Players do *not* report absolute time (they don't know it), but how many milliseconds they have been playing since the last request. So when you seek to a position P in seconds, LMS stops playback, seeks N bytes into the file to its best estimation of where is P seconds and starts sending a *new* track to the player from byte N+1. LMS then starts to count time from the estimated position using an autonomous counter and adjust that counter when it receives the player's actual played time which has started at 0 second with first bytes received, so at byte N+1 of the actual file This explain why playback counter it often not very precise, it's just an indication sometimes and especially jumping 10s before the end of a track is unlikely to display things properly.
