<p>Function that parses a input string to a time value.<br/>
The string format is following the ISO 8601 specification for durations: [-]P[nY][nM][nW][nD][T[nH][nM][nS]]<br/>
Some examples to illustrate how the string is converted to a timeperiod, expressed in seconds:<br/>
P1Y = 1 year = 365 days = 31536000 seconds P1M = 365/12 days = 2628000 seconds P1W = 1 week = 7 days = 604800 seconds -P1D = -1 day = -86400 seconds PT1H = 1 hour = 3600 seconds -PT1000000S = 1000000 seconds P1M1WT1H = 1 month + 1 week + 1 hour = 3236400 seconds It pretty strictly checks the spec, with a few exceptions:</p>
<ul>
<li>A week field ('W') may coexist with other units.</li>
<li>Decimal values are not supported.</li>
<li>The alternate format as a date and time is not supported. </li>
</ul>
