01

Establish one event timeline

Two records with similar displayed times do not necessarily describe the same sequence. Compare the controller clock, historian clock and operator log basis before deciding which event happened first. Keep the original exports rather than changing timestamps in the only available copy.

02

Record offsets and resolution

Note the time zone, clock offset, recording interval and any known adjustment for each source. Distinguish an event timestamp from the time an operator entered a note. Our recommendation is to keep an original-time column and a separate aligned-time column, together with the reason for each correction.

03

Link observations without overstating causation

Use available collector readings and production records to identify a possible sequence. EPA’s monitoring overview describes multiple fabric-filter indicators [2]; it does not say that a particular alarm proves a particular failure. State which links are observed and which remain hypotheses requiring equipment review.

04

Keep a reviewable incident pack

Include the original extracts, the alignment method, the affected operating state and outstanding questions. Ask the responsible supplier to identify additional records needed for diagnosis. This develops the archive’s performance-review topic [1] into an evidence workflow without prescribing alarm thresholds or changing the control sequence.

FAQ: Is a screenshot enough to establish order?

Only if its time basis and resolution support the comparison. Preserve the underlying record where available.

06

FAQ: Should old timestamps be overwritten?

Keep the original and document any alignment separately so another reviewer can reproduce the interpretation.
