Customer says: " I was using mysql timestamp "now()" in the mysql query. I
changed this to a php timestamp "$now = date("Y-m-d H:i:s");" and it remains
the same."
If we reboot the server then it comes right but over the day, the 'clock' and
'date' results get out of sync again.
The server is a VM on an ESXi host and all hardware uses the domain controller
for NTP.
I have checked the host and domain controller times and they are in sync.
Hwclock is in line with the host time.
Odd ...
Thanks
Colin
