Is the system clock set to UTC?
$ cat /etc/default/rcS
You should see a line
UTC=yes.
I don't know if this matters, and with a tz of London it shouldn't account for 5 hrs.
Is 09:45 the time the process starts or the time it completes and mails output? Perhaps add a line to the script that prints the date at the beginning and the end, e.g.
echo "Script starting"
date
...
echo "Script ending"
date
Then check the headers on the email message.
