Palo Alto's morning is India's late evening
Palo Alto keeps Pacific Standard Time, UTC−8, from the first Sunday in November to the second Sunday in March, and Pacific Daylight Time, UTC−7, the rest of the year. India is thirteen and a half hours ahead in winter and twelve and a half in summer. A lab manager who writes at 09:00 in Palo Alto reaches a Bengaluru desk at 22:30 IST in winter and 21:30 IST in summer.
The 24-hour window softens that gap: the client's message stays open for replies until the same time the next day, so a morning shift in India can still answer free-form. What the window does not soften is the marketing rule. News about a new service goes to Palo Alto by email or a call; on WhatsApp, the thread carries the shipment, the ticket and the invoice.
