I have a phone but i dont really need it, but other people i have a lot of respect for need me to have a phone ( to a degree if i dident have one they would buy one for me )
You should also be able to set it with a tablet ( android or IOS ) if you have such a thingy,sadly windows dont seen to be supported on devises.
If push come to shove you could get a friend with a devise to do the settings up once, after that bar summer / winter time there are little reason to "log" into the camera.
While i myself do have date/time embedded in the footage of my dashcameras, then it is not really needed, if it was not a option i would not miss it.
