Belated thanks for that reply JCL. I can confirm that the Dropbox idea seems to work well, contingent on the VPS time matching the time zone.

I had some issues because windows seems to currently think UTC is one hour ahead of where it actually is. I changed the VPS time zone to match my home time zone and the issue seems to have resolved itself.

However, I have noticed that when I have two or more Zorros trading on two or more brokers via MT4 on my VPS, they often display different times and exchange rates in the Server window of the Zorro interface. For example, I have an IC Markets and Global Prime MT4 running on one VPS. The IC Markets UTC time is correct, but Global Prime is an hour slow. Also, it seems that the server window doesn't update in real time, as if it gets frozen. For example, I can see that the server window is currently displaying the time from 11 minutes ago and the corresponding EURUSD price from that time.

What could be causing this? Can it affect live trading? Importantly, the message window seems to update in real time as it should. Its just the server window that seems to lag.
