Lazarus Timer for Clock
« on: September 10, 2015, 05:24:24 pm »
Hello There!

In my project, after login process is completed, the server sends me a string containing its current time (sometimes off by a few seconds if the connection lags). After i receive it, I use it as the initial time for a clock i update every second using a Timer.

However, whenever the GUI is blocked/halted, the timer "ticking" procedure also stops. I have an idea that maybe i need to run the timer in a different thread, but i have no clue on how to properly implement it.

Any help?

Would storing the delta value between the client system time and the server time work?

Then you can get the server time using something like: Now + FServerDelta

I don't think using a thread is going to solve you problem, but if you want to, FPC includes a thread based timer in the fptimer unit.

TTimer doesn't stop when for example ShowMessage() or TOpenDialog is opened.

like `Geepster` suggested, implementing a delta value operation between local and server time is the best and simplifies the program a lot.
