The new value, in seconds.
Errors: Possible errors include @ref GLFW_NOT_INITIALIZED and @ref GLFW_INVALID_VALUE.
@remark The upper limit of GLFW time is calculated as floor((2<sup>64</sup> - 1) / 10<sup>9</sup>) and is due to implementations storing nanoseconds in 64 bits. The limit may be increased in the future.
This function may be called from any thread. Reading and writing of the internal base time is not atomic, so it needs to be externally synchronized with calls to @ref glfwGetTime.
@sa @ref time
Added in version 2.2.
Ingroup: input
Sets the GLFW time.
This function sets the current GLFW time, in seconds. The value must be a positive finite number less than or equal to 18446744073.0, which is approximately 584.5 years.
This function and @ref glfwGetTime are helper functions on top of @ref glfwGetTimerFrequency and @ref glfwGetTimerValue.
