伍分 is the formal written form of 'five fen' (or 'five minutes'), using the financial anti-fraud character 伍 instead of the ordinary 五. You'll see 伍分 on banknotes, checks, contracts, and official documents where preventing alteration is important. The POS tag 't' (time) in this row is likely an error — in typical usage it is a noun or measure phrase used for either monetary amounts or time intervals.
