duration — Calculates the number of seconds of a given time period
package require nstcl-time ?1.0.1?
package require nstcl ?1.0?::nstcl::duration ?-nocomplain? ?-absolute_value? ?-default default? period
This function returns the number of seconds of a given period of time. For example, duration "1 day" would return 86400. period can be in any format understood by [clock scan].
- -absolute_value
- If this switch is present, and the duration is a negative number (for example, duration "1 hour ago"), the absolute value will be returned instead.
- -default (defaults to 0)
- This switch specifies what value should be returned if period cannot be parsed, and the -nocomplain option was used.
- -nocomplain
- If this switch is specified, and period cannot be parsed by [clock scan], then rather than generating an error, the value given to the -default switch will be used.
