Sources of time specific to Twitch and Kick

Besides subs, bits and donations, three things can add time: channel points (Twitch and Kick), hype trains (Twitch) and KICKs (Kick). Everything is set in Time Settings, Twitch or Kick tab, and nothing adds time until you give it a duration.

Twitch channel points

In Time Settings, Twitch tab, Channel points card, click Allow channel points on Twitch. You go through Twitch, then come back.
Set a default time, in seconds per redemption.
Click Import my Twitch rewards, tick the ones that should add time, then Add the selected rewards.
Give a reward its own time if you want, then save.

Only the rewards in the Rewards that add time list count: "Hydrate" adds nothing unless it is there. Empty time = the default time, 0 = no time. The cross removes a reward from the list.

Kick channel points

Same idea in the Kick tab, Channel points · Kick card, with one difference: titles are typed by hand, exactly as on Kick. No extra permission is asked for.

Kick can report the same redemption more than once, for instance pending and then accepted or rejected. Marathon-Timer counts the first notice that is not a rejection, and only once per redemption.

Twitch hype trains

Twitch tab, Hype train card, click Allow hype trains on Twitch.
Set the seconds per level reached, then save.

Each level counts once, level 1 included, as soon as Twitch reports it. If Twitch skips a level between two notices, it is caught up: a train going from level 2 to level 4 does add levels 3 and 4.

KICKs on Kick

Kick tab, KICKs card: Add X seconds for N KICKs, 100 by default. The time is proportional to the amount gifted, like bits: with 60 seconds for 100 KICKs, a 500 KICKs gift adds 5 minutes.

With the rest of the timer

These sources show up in the happy hour, the time multiplier and the rate card, like any other event.
The per-event cap in Set Timer applies to them too.
KICKs count in the Stream Boss (1 HP per KICK) and in the revenue estimate.
