Hello!
Unless you've changed things with Grub Customizer, GRUB2 defaults to the one that's at the top of the list - the one saying "Ubuntu". It also has an asterisk preceding it.
The others that have 'generic' in the name are 'advanced options' - usually used if a newly-updated kernel gums up. This is rare, but it DOES happen. This lets you start up to the previously working kernel, so you can reinstall the broken one (to see if that fixes things).
The other option after the second one is the previous kernel in what is called 'recovery mode'. This mode brings up a menu that lets you do things like a disk integrity check (fsck), fix broken packages (dpkg), and open a command shell (bash).
More info can be found through Google, or here:
https://wiki.ubuntu.com/RecoveryMode
As people accumulate kernel update after kernel update, they are fairly large, so they start taking up more and more space on the hard drive. When that happens, they use 'Install/Remove Software' (Synaptic Package Manager) to remove the no-longer-needed kernels.
There are also terminal commands to remove old kernels that can be automated. They can be found by Googling 'remove old Linux kernels'. We can talk more about THAT when more of you n00bs start experiencing disk space issues.
You only asked for the time, but you now know how to build a watch...
