This is my very first post to EE and trust me, i know nothing about java at all. I really dont know if i am asking this question in the right topic area but i am desprate to get any possible help. Now let me explain my problem to you. my company is running a billing application based on java (that i dont have source code of) with oracle 9i as database ( OS platform = Redhat linux 9.0) in Quetta, Pakistan. In pakistan we dont have the daylight saving time change (no forward or backward of clocks). Thogh my system's clock and timezone are properly configured (PKT or GMT+5) as well as oracle's time and timezone settings(NTP not implemented), a few days back the clock on the java application forwarded 1 hour with out any change in application or java while the system and database times are correct. This is causing a lot of problems for me becuase all the time based features of the application are effected. Since our support contract with the developer has expired its now up to me to find a solution and being a network engineer only i have no idea what to do or where to look for help. So please please please help me on this issue.
