Expected Stream time command.
While !time gives the amount of time til next stream, it would be nice to also get the expected time of that stream as well, or a command to get that.
Since you have that information in order to calculate the ttns, it should be easy to add.
I don't know what info insobot can get about the timezone of the user, or if it can display a different timezone to each user, so it would probably need to settle on Caseys timezone, or a specific one at least.
I've made an attempt with 3eeecc2c2bda0df0183bf13d1e4cab4ecffa70d7 - !time now accepts a timezone argument, e.g. !time London and it'll print an absolute time instead of the usual output:
20:44 <insofaras> !time London
20:44 <insobot> Next stream: Sat 13 Jun 7:00 pm BST (5655 minutes from now)
It should accept any name from the TZ Database Name column here: https://en.wikipedia.org/wiki/List_of_tz_database_time_zones, with the parts before the slash being optional.
EDIT: I should mention there is also !schedule which will show the stream day + times for the current week in Casey's timezone.
