Hours alongside berth by gateway

tt009.gateway.berth-hours observed

Time alongside a berth — the denominator of the UNCTAD/World Bank waiting rate.

Withdrawn from publication

WINDOW-CLIPPED. Berth durations are floored by the length of the archive, not measured: 34% of berth hours sit in stops reading the full archive length, where a genuine container call runs 12-48h. Inflates the figure and so deflates the waiting rate. Usable once the archive is long relative to a call.
