Returns the GLFW time.

function glfwGetTime() : float

This function returns the current GLFW time, in seconds. Unless the time has been set using glfwSetTime it measures time elapsed since GLFW was initialized.

This function and glfwSetTime are helper functions on top of @ref glfwGetTimerFrequency and glfwGetTimerValue.

The resolution of the timer is system dependent, but is usually on the order of a few micro- or nanoseconds. It uses the highest-resolution monotonic time source on each supported platform.


float The current time, in seconds, or zero if an error occurred.
