Clock skew and sentinel timestamps

Device clocks are wrong; bidstream timestamps can be in the future or negative; missing values default to 1970-01-01 (the temporal 'zero-island'); rounded values pile up at 00:00:00. These are not real slots.

Class

Case to account for

Affects

1 conversion

Detection

Timestamps at epoch 0, in the future, or spiking at midnight.

Mitigation

Bound-check and flag or drop sentinels; never bucket 1970 or a future time as a real slot.

Affected conversions

Timestamp + zonehour-of-week slot
