Question

why is standard time more scientific than local time​

Answer 1

It is the time, reckoned on the basis of the meridian running through a particular place. ... When the sun is exactly over the head, it is noon at that place. Noon occurs at different times in different meridians. Hence local time varies from region to region.

so standard time is important

Answer 2

Answer:

Recording observations in local time could be confusing, because it varies from point to point, even for small changes in east-west location.

Data transmission requires an even further case of all points in a system using exactly the same time. The same goes for astronomical observations (e.g. parallax).

The few cases where local time may be useful is in recording the time of occurrences, such as sunrise and sunset, and moonrise and moonset, that can vary considerably from the standard time being used. Also, some observations must be taken when the Sun is at its zenith, which is noon, local time.
