Does Singapore use Daylight Saving Time?

Singapore's location approximately one degree north of the equator means daylight hours remain nearly constant across the seasons, removing the original rationale for DST entirely.

China, Hong Kong, Taiwan, Malaysia, and Western Australia all operate on the same UTC+8:00 offset as Singapore, though each uses its own regional designation — CST, HKT, CST, MYT, and AWST respectively.
