- Not available on that edition (the reason is in the tooltip)
- Depends on the setting, your class or another addon (details in the tooltip)
What it does
Checks how many seconds are left on the totem you choose, compared with the number of seconds you set. A totem that is not active does not match.
Why you might use it
For Shamans, compares the seconds left on a specific totem, so you can refresh it before it runs out, for example recasting Windfury Totem with less than 10 seconds left. An absent or expired totem does not match. On Retail and WoW Forever the game can hide totem slots, and the condition is unavailable then. See also Specific Totem Present and Totem Time Remaining.
Example
Windfury Totem is active where the remaining time is less than 10 seconds
Settings
What each setting in the condition editor means, from the game's own help.
Totem - The active totem to check. Unticked, Use this exact spell rank matches its localized name across ranks. Ticked, it requires the native spell ID; name-only observations are unavailable.
Operator - How to compare Specific Totem Time Remaining with the Seconds value. This comparison uses basic mathematical comparison operations.
Seconds - Compare the active totem's remaining seconds with this amount. An absent or expired totem does not match; unavailable observations stay unavailable.
