+# By default, OfflineIMAP will not exit due to a network error until
+# the operating system returns an error code.  Operating systems can sometimes
+# take forever to notice this.  Here you can activate a timeout on the
+# socket.  This timeout applies to individual socket reads and writes,
+# not to an overall sync operation.  You could perfectly well have a 30s
+# timeout here and your sync still take minutes.
+#
+# Values in the 30-120 second range are reasonable.
+#
+# The default is to have no timeout beyond the OS.  Times are given in seconds.
