=== Converting DTIM time to normal time ===

The field consists of two values (v[0] and v[1]) separated with a space (0x20). Sample code:

<syntaxhighlight lang="c">

// time in seconds - "concatenate" date & time elements with a decimal point delimiter

TimeInSeconds = (v[0] * (2^32) + v[1]) * 10^(-7);

// shift basis from Jan 1, 1601 to Unix epoch Jan 1, 1970 (369 years & leap days)

UnixTimeStamp = TimeInSeconds - 134774 * 24 * 3600;

</syntaxhighlight>
