This is a low-priority RFE. My servers tend to have long uptimes, and when they reboot, I often want to know what happened just before that. So, I find myself typing journalctl --since today quite often. It would be nice to have a shortcut, and -t isn't used. I know this is a slippery slope, but we already have -b, and this seems likely to be pretty common for more people than me.
Well, but the next guy then wants -w for --since=-7days, and another one wants -t to be --since=-24h and so on... I am not convinced we should give one of them a shortcut...
I know it's got to end somewhere, but what are shortcuts for? :) I've already got some aliases, so I don't think there's a real need to push very hard on this one; I just see "-b" being given a lot party because it's so short and handy, and I think often "--since=today" would actually be more helpful but isn't used because of the typing (particularly when recommending it to someone else).
OK, I am not convinced we want this. Sorry. Closing.
