It is possible that the code being utilized is fetching data from a live database with values that are continuously increasing.
To see an example of how a simple timer can work, take a look at this example on js fiddle that I created. Notice that even if you click "Run" multiple times, the time will remain constant.
If you want to save values across browser refreshes, consider using localStorage. You can learn more about it by reading W3 School's article on the topic.
In my own implementation, I utilize
localStorage.setItem("time", currentTime); // Remember that currentTime must be a string!
Include this line in each iteration of your code after defining the currentTime variable.
Upon starting your application, a simple if statement like this
if (localStorage.getItem("time") {
CurrentTime = localStorage.getItem("time");
} else {
// set default values
}
should suffice, as localStorage.getItem returns null when the value does not exist (or if you manually set the value to null).
(When working with localStorage, you can also use [bracket notation], which is commonly seen in examples)
localStorage["foo"] = "value";
// is equivalent to:
localStorage.setItem("foo", "value")
// and
var bar = localStorage["foo"];
// is equivalent to:
var bar = localStorage.getItem("foo");
