The server sends clients a Packet 0xB1 to tell them the current time on the server (upon request from the client). The clients send Packet 0xB1 to request said timestamp from the server.<br />

===Timestamp Format===<br />
C code to format the timestamp (from a struct timeval (rawtime) and struct tm (cooked)):<br />
<pre>sprintf(pkt->timestamp, "%u:%02u:%02u: %02u:%02u:%02u.%03u",<br />
cooked.tm_year + 1900, cooked.tm_mon + 1, cooked.tm_mday,<br />
cooked.tm_hour, cooked.tm_min, cooked.tm_sec,<br />
(unsigned int)(rawtime.tv_usec / 1000));</pre><br />
