I have netdate, rather than rdate, which works fine. But a couple of 
questions...what's your timezone set to? Does typing 'date' report GMT or 
BST ? What does "/sbin/clock -r" (or hwclock --show) say? Is it correct 
in being an hour ahead (or behind)?

Most time sync programs *will* return the date/time in GMT and let the 
system deal with the TZ conversion...

Servers I sync on are: ntp2a.mcc.ac.uk, ntp2b.mcc.ac.uk, ntp2c.mcc.ac.uk, 
ntp2d.mcc.ac.uk and ntp.cs.strath.ac.uk.
