A five minute recording is all it takes to tell what time day and year it is at home. Natural sounds like backyard native birds like Collared Kingfisher, Philippines Pied Fantail, Zebra doves, and Yellow-vented Bulbuls are busy asserting their territory and finding food in the morning before it gets too hot. 

Migratory birds like Gray Wagtail, Arctic Warbler, and Ashy Minivet mean that it's sometime during their busy winter migration. Human sounds also provide great clues. People sweep streets by hand with a local broom called walis tingting before it gets too hot and motorcycles rev past during the busy rush hour.
