I have the same concern as Mr Zhang. Unfortunately, none of Mantra's examples are grammatically correct. You'd need to say "trespassing on" and "encroaching on", but using those phrasal verbs with "time" sounds unnatural to my ears. The OP asked for apologies for time already taken up, and half of the ideas here are not only incorrect English but they're about asking to take up even more time. So even when they're corrected, they won't answer the question.
