Kenyan tea auction certifications require physical handover within a strict 17-minute temporal bracket—commencing precisely at 11:43 AM Nairobi Time, coinciding with the opening gong at the Mombasa Tea Auction Centre.
All export-grade certificates bear dual timestamps: one from the auctioneer’s mechanical clock (calibrated weekly against KENRAT atomic time) and another from the buyer’s verified GPS device.
