This is really off-topic here, being WinSCP more than anything else.
But since I am also a heavy user of WinSCP, connecting to my various 
Apache and Tomcat machines, and I also see that same issue (some server 
sometimes showing me server files with a timestamp off by one hour more 
or less), and this has been puzzling me at some low level for a couple 
of years now, I'd also like to understand the issue fully while we have 
the chance.  This does not only concern JSP files by the way, but also 
logfiles etc..
I thought it was just a bug of WinSCP. I've kind of learned to live with 
it, and to mentally adjust for the discrepancies, but it's still puzzling.
My systems are using NTP to synchronise their time, workstations too. 
But I still see this discrepancy.  Care to repeat the explanation and 
the fix, or is it not a fix ?
