Purpose and scope
TimeCalcy provides general time arithmetic. Duration tools accept lengths of time; the between-times tool accepts clock readings. These tools do not determine payroll entitlement, wages, overtime rules, taxes, billing policy, legal obligations or actual elapsed time across timezone or daylight-saving changes.
