Date anchoring

Under-specified date inputs ("2026", "2026-03", "2026-03-15") are anchored to your company’s IANA timezone, set on the Company resource and defaulting to Europe/Oslo. "2026-03" from a company in America/Los_Angeles resolves to the start of March 2026 in LA, not UTC. Each Activity records the timezone that was used on Activity.timezone for provenance; period filters (YTD, MTD, specific years) bucket from your company’s timezone. To avoid start/end snapping, supply a full ISO-8601 timestamp (2026-03-01T00:00:00). The wall-clock time is interpreted in the company’s timezone — an offset in the input (…-08:00, …Z) does not override it.
