PDT vs SGT — cities and working rhythm
US West Coast summer offset (mid-March to early November), UTC-7. During PDT, the 7-h gap with UTC / London simplifies daylight-hour overlap — 9 AM PT = 5 PM London (BST).
Singapore / KL / Manila business hub — Southeast Asia's regional HQ zone. Business hours 9 AM – 6 PM SGT. Overlaps well with India (early SGT afternoon = late IST afternoon) and Australia (late morning SGT = early afternoon AEDT). Long time gap with the US means transactions bridging Singapore / SF are usually async.
Time gap: SGT is 15.0 hours ahead of PDT (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
