# Ref/Attrib: ISO-8601:2004(E), §4.4.4.2 Representations of time intervals by duration and context information
# Note: "1 month" ("P1M") is assumed to be "30 days" (see ISO-8601:2004(E), §2.2.1.2)
# Usage: timeDuration [arg1] ([arg2])
+ # Version: 1.0.1
# Input: arg1: seconds as base 10 integer >= 0 (ex: 3601)
# arg2: precision level (optional; default=2)
# Output: stdout: ISO-8601 duration string (ex: "P1H1S", "P2Y10M15DT10H30M20S")
# Example: 'timeDuration 111111 3' yields 'P1DT6H51M'
