Did you know LTA gives bus arrival times down to the second? Neither did I, until I poked at LTA's DataMall API. They politely ask developers to round down to the nearest minute and slap "Arr" on anything under a minute away — but where's the fun in that?
So here it is: the full, unadulterated, second-by-second data, served up as Highly Precise But Probably Inaccurate Bus Timings.
Disclaimer: this is for entertainment only. The developer — and, speaking unilaterally on their behalf, LTA — accepts no responsibility for missed buses, missed dates, missed flights, missed opportunities, or any other consequence of trusting a number that ticks down to the second. If you sprint for a bus and it's already gone, that's between you and your shoes.
