There are 15 degrees of longitude in each standard time zone
Indian Standard Time (IST) is measured at 82.5 degrees east longitude, which corresponds to five and a half hours ahead of Coordinated Universal Time (UTC+5:30). It is the time zone used in India and Sri Lanka.
If the chronometer reads 8 AM Pacific Standard Time at solar noon, it indicates that your location is 120 degrees west longitude. This discrepancy in time suggests that you are 2 hours away from the Pacific Time Zone (120 degrees west longitude corresponds to a 2-hour time difference from Pacific Time).
5.5 * 15 = 82.5 82.5° east longitude
IST = India Standard Time The longitude bounds is 68 degrees East - 97 degrees East. The latitude bounds is 35 degrees North - 8 degrees North
If it's noon solar time at 90 degrees W longitude, every 15 degrees of longitude represents a one-hour time difference. So, at 72 degrees W longitude, the solar time would be 2 hours behind (2:00 PM).
The central meridian for Eastern Standard Time (EST) is 75 degrees west longitude. This meridian serves as the reference point for the time zone, which is 5 hours behind Coordinated Universal Time (UTC-5).
Lines of longitude are used to divide the Earth into 24 time zones, each approximately 15 degrees wide. The Prime Meridian (0 degrees longitude) serves as the reference point for Coordinated Universal Time (UTC), which is the basis for setting world standard time. Each time zone is determined by the number of hours ahead or behind UTC they are, making it possible to convert local times to a standardized global time.

England's Royal Observatory in Greenwich (the source of Greenwich Mean Time - GMT) is 0 degrees longitude and the reference point. 120 degrees East is the longitude of the east coast of Taiwan. At that longitude, 1/3 of a circumference from Greenwich, the standard time (and date) should be 8 hours ahead of Greenwich. So if it is 4am in Greenwich, it should be noon in Taiwan.
