String to Duration

StreamableKNIME Date and Time Handling version 4.4.0.v202106241857 by KNIME AG, Zurich, Switzerland

Converts string cells to duration cells. The string representation of these durations needs to be in either the ISO-8601 representation (see date-based duration format or time-based duration format for details, e.g. 'P2Y3M1D'), the short letter representation (e.g. '2y 3M 1d'; Date-based duration: y: years, M: months, d: days; Time-based duration: H: hours, m: minutes, s: seconds) or the long word representation (e.g. '2 years 3 months 1 day').
