we don't have to....

just bro egg used to wrong chinese word to mean forward & backward for the time....

Hmm....seems he has wrong concept about forward & backward, not because of the wrong chinese word.

flora, 未必係錯架，可能好似 "前" 咁，有雙重意思

其實米奇個問題問得好架。現在2pm，叫你較早兩個鐘，咁你會點較呢？如果睇帶或DVD,呢個更容易。所有戲開頭都有電影公司Logo，最後係所有參與工作人員名字。所以睇番前d，前等於接近開頭果部份，所以會用backward 去形容應該往那裡去。如果有一套戲90分鐘，以中間45分鐘為中間點。如果你話要睇番前半段，咁我係唔係要俾你睇45至90分鐘果段你睇呢？

Nope.....

Maybe....but I think most of the ppl will use "fast" or "slow" for time switching.....not "early" or "late"

多數嚟講係。但我間唔中會用 "較早"/"較遲" (而唔係 "較前"/"較後"，而冇諗過會有混淆嘅機會架喎，直到阿蛋個 case，先知原來有部份人係會將 "較早一個鍾" 當作等同 "較快一個鍾" 或 "加多一個鐘"

yeah....that's why those ppl will confuse others

咁如果叫你 "去前啲" 呢?

"前後" 之所以 confusing 係因為 "前" 可以解 "之前" 亦可以解 "前方"，係兩個唔同嘅方向，所以係阿蛋所講嘅 "concept" 問題。 但 "早兩個鐘" 點解可以係會理解為 "兩個鐘後" 呢？ 我仲未推理到，不如阿蛋講解下?  咁如果將開會時間較早兩個鐘開（原本係 2pm)，你會係 12pm 去定 4pm 去呢?  

我會理解為12PM, 因為係有提前/提早的意思嘛; 但如果你講將時鐘教早2 個鐘, 咁我理解為4PM, 因為有forward的意思

where is the concept went wrong????
