We really use timestamps in IRC everywhere. So incorrect time will cause quite a number of issues:
 * Temporary KLINES/GLINES/SHUNS/etc will not expire correctly. They might expire like an hour earlier, or even directly when they are added, or later.
 * Sudden (wrong) nick collision kills. Incorrect time can be exploited by someone to kill other users (thus incorrect time is a security problem as well!)
 * Channels might not show up in /LIST (especially if time is more than a day off)
 * Services might be unable to set a user +r (+r = register user)
 * In /WHOIS it may look like someone 'signed on' at the wrong time, even in the future
