Function strToTime
Description
string require('workDate').strToTime( string time [, int now ] );

Parameters
text
A date/time string. Valid formats are explained in Date and Time Formats.
now
The timestamp which is used as a base for the calculation of relative dates.
Returns
Returns a timestamp on success.
Examples
console.log( workDate.strToTime() );
console.log( workDate.strToTime('now') );
console.log( workDate.strToTime('10 September 2000') );
console.log( workDate.strToTime('+1 day') );
console.log( workDate.strToTime('+1 week') );
console.log( workDate.strToTime('+1 week 2 days 4 hours 2 seconds') );
console.log( workDate.strToTime('next Thursday') );
