For telling time, 差 means 'short of': 差十分三点 = 'ten minutes to three' (2:50).

Components

radical
工 gōng
work; tool
The 工 radical at the bottom serves as the indexing handle and represents a measuring tool - a carpenter's square. Combined with the sheep above, the character pictures the act of measuring and grading livestock. The discrepancies revealed by such measuring became the abstract 'difference, lack.' Indexing radical.
semantic
羊 yáng
sheep (compressed form)
The upper portion is a compressed 羊 (sheep) - head and horns visible. Combined with the 工 (work/tool) component below, the original character depicted measuring or selecting sheep, comparing one to another. From 'comparing/sorting' came 'difference,' and from notice of inequality came 'poor, lacking.'
