+Subject: [PATCH] Fix <time.h> check
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+We're conditionally including based on HAVE_TIME_H in a bunch of places,
+but we're not actually checking for time.h, so that's never going to be defined.
+
+While at it, add in a missing include in the cram plugin.
+
+This fixes a bunch of implicit declaration warnings:
+```
+ * cyrus-sasl-2.1.28/lib/saslutil.c:280:3: warning: implicit declaration of function ‘time’ [-Wimplicit-function-declaration]
+ * cyrus-sasl-2.1.28/lib/saslutil.c:364:41: warning: implicit declaration of function ‘clock’ [-Wimplicit-function-declaration]
