The sun sets where I am at ~430pm during the winter in standard time. I don't really see how having the sun set at 530pm instead would have a substantial effect on bedtime. There is so little sunlight in the winter that work/social life are what drive wakeup and bedtime. I imagine this isn't as true in India. Is there any research that accounts for the actual length of daylight available?

Talking about the whole year, not just the winter. In Summer later sunset affects bedtime. In winter later sunrise affects rise time.

The proposal will only change the winter though, we are already only on standard time for 4 months of the year.

We're talking about whether permanent ST is better than permanent DST, not DST switching vs not switching.
