### isotime Format
Formatting for the function <code>isotime &#96;&lt;format&gt;&#96;</code> uses the magic reference date **Mon Jan 2 15:04:05 -0700 MST 2006**, which breaks down to the following:
<table border="1" cellpadding="5" width="100%">
<tr bgcolor="lightgray">
<td></td>
<td align="center"><strong>Day of Week</strong></td>
<td align="center"><strong>Month</strong></td>
<td align="center"><strong>Date</strong></td>
<td align="center"><strong>Hour</strong></td>
<td align="center"><strong>Minute</strong></td>
<td align="center"><strong>Second</strong></td>
<td align="center"><strong>Year</strong></td>
<td align="center"><strong>Timezone</strong></td>
</tr>
<tr>
