| PASS Active time in after phase with backwards-only fill is unresolved | |
| PASS Active time in after phase with forwards fill is the active duration | |
| PASS Active time in after phase with forwards fill, zero-duration, and infinite iteration count is the active duration | |
| PASS Active time in after phase with forwards fill and positive end delay is the active duration | |
| PASS Active time in after phase with forwards fill and negative end delay is the active duration + end delay | |
| PASS Active time in after phase with forwards fill and negative end delay greater in magnitude than the active duration is zero | |
| PASS Active time in after phase with forwards fill and negative end delay greater in magnitude than the sum of the active duration and start delay is zero | |
| PASS Active time in after phase with 'both' fill is the active duration | |
| PASS Active time when the local time is unresolved, is unresolved | |
