ttrue

The time period for which a boolean stream is true before turning false

The time that a stream spends in the true state. This transform uses the timestamp, so the timestamp is displayed in the sequence:

[
    {"t": 1, "d": true},
    {"t": 2, "d": true},
    {"t": 4, "d": true},
    {"t": 5, "d": false},
    {"t": 6, "d": false},
    {"t": 7, "d": true},
    {"t": 8, "d": false},
    {"t": 9, "d": true}
]

Given the above data, we can get the following:

ttrue
[
    {"t": 5, "d": 4},
    {"t": 8, "d": 1}
]

The stream was true from timestamp 1 to 5, when it changed to false. So the total time the stream was true was 4 seconds. The stream then turned true at timestamp 7, and turned false at timestamp 8, meaning that it was true for 1 second. Finally, the stream turned true at timestamp 9, but we don’t know how long it was true, so ttrue does not return anything for this final part.
