This example shows the difference between calling \hyperlink{group__Ecore__Time__Group_ga98f2439b5d3e7114a75bfe2f0c22c4e9}{ecore\+\_\+time\+\_\+get()}, \hyperlink{group__Ecore__Time__Group_gab53d952cc4c2f3ed032d535b307c43bd}{ecore\+\_\+loop\+\_\+time\+\_\+get()} and \hyperlink{group__Ecore__Time__Group_ga0b8030aa39eb3701b6b30816ee9c45df}{ecore\+\_\+time\+\_\+unix\+\_\+get()}.

It initializes ecore, then sets a timer with a callback that, when called, will retrieve the system time using these 3 different functions. After displaying the time, it sleeps for 1 second, then call display the time again using the 3 functions.

Since everything occurs inside the same main loop iteration, the internal ecore time variable will not be updated, and calling \hyperlink{group__Ecore__Time__Group_gab53d952cc4c2f3ed032d535b307c43bd}{ecore\+\_\+loop\+\_\+time\+\_\+get()} before and after the sleep() call will return the same result.

The two other functions will return a difference of 1 second, as expected. But \hyperlink{group__Ecore__Time__Group_ga0b8030aa39eb3701b6b30816ee9c45df}{ecore\+\_\+time\+\_\+unix\+\_\+get()} returns the number of seconds since 00\+:00\+:00 1st January 1970, while \hyperlink{group__Ecore__Time__Group_ga98f2439b5d3e7114a75bfe2f0c22c4e9}{ecore\+\_\+time\+\_\+get()} will return the time since a unspecified point, but that never goes back in time, even when the timezone of the machine changes.

\begin{DoxyNote}{Note}
The usage of \hyperlink{group__Ecore__Time__Group_gab53d952cc4c2f3ed032d535b307c43bd}{ecore\+\_\+loop\+\_\+time\+\_\+get()} should be preferred against the two other functions, for most time calculations, since it won\textquotesingle{}t produce a system call to get the current time. Use \hyperlink{group__Ecore__Time__Group_ga0b8030aa39eb3701b6b30816ee9c45df}{ecore\+\_\+time\+\_\+unix\+\_\+get()} when you need to know the current time and date, and \hyperlink{group__Ecore__Time__Group_ga98f2439b5d3e7114a75bfe2f0c22c4e9}{ecore\+\_\+time\+\_\+get()} when you need a monotonic and more precise time than \hyperlink{group__Ecore__Time__Group_gab53d952cc4c2f3ed032d535b307c43bd}{ecore\+\_\+loop\+\_\+time\+\_\+get()}.
