Changing time with arrows on web is finicky

[ahenrici]

I am having my astronomy students use the program for several labs and whenever they try to change the dates or time using the arrows it sometimes won't work no matter how much we click. Is it possible to have it where we can type in the information as well?

Not that I could help here, but you could describe your circumstances a bit better. Operating system, browser version? I see zero problems on Win11+Firefox 117.0.1.
