I don't think that's the case for mine.  Here's an example of a 14 minute delay after receiving a notify:

06-Aug-2012 11:20:36.575 notify: client view hc: received notify for zone 'uts-sa.mydomain.ddns': TSIG ''
06-Aug-2012 11:34:36.177 general: zone uts-sa.mydomain.ddns/IN/all: Transfer started.
06-Aug-2012 11:34:36.178 xfer-in: transfer of 'uts-sa.mydomain.ddns/IN' from connected using
06-Aug-2012 11:34:36.184 general: zone uts-sa.mydomain.ddns/IN/all: transferred serial 2010585436: TSIG ''
06-Aug-2012 11:34:36.184 xfer-in: transfer of 'uts-sa.mydomain.ddns/IN' from end of transfer
06-Aug-2012 11:34:36.185 notify: zone uts-sa.mydomain.ddns/IN/all: sending notifies (serial 2010585436)
