CET vs SGT — cities and working rhythm
Most of continental Europe — DACH, Benelux, France, Iberia, Nordics (except Finland), Poland, Czech Republic. Business hours 9 AM – 5:30 PM CET, with a longer lunch (12:30 – 2 PM) in southern countries. Winter: CET (UTC+1); summer: CEST (UTC+2). Big lag against North America — early morning CET overlaps late night ET.
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 7.0 hours ahead of CET (standard-time offsets — daylight-saving flips shift this by an hour twice a year in most northern-hemisphere zones).
