About these time zones
IST. India Standard Time is UTC+5:30 all year with no daylight saving, and covers the whole country. The half-hour offset means India-facing meetings often start on the half hour.
PST. Pacific Time is PST (UTC-8) in winter and PDT (UTC-7) in summer, on the same US daylight saving dates as Eastern Time. It covers Los Angeles, San Francisco, Seattle and Vancouver.
Overlap. There is no hour that falls inside a 9 to 5 working day in both zones, so one side has to meet early or late. Early morning in one zone and early evening in the other is usually the least painful option.
