Description
Return minimumDuration=endAt-latestStart, maximumDuration=endAt-earliestStart, and width=latestStart-earliestStart.
Laboratory records distinguish specimen identity, sampling coverage, retained quantities, processing times, image scale, and measurement uncertainty. Areas, volumes, counts, and source-support flags measure different aspects of a record. A local calculation does not identify tissue or establish diagnostic adequacy.
Return minimumDuration=endAt-latestStart, maximumDuration=endAt-earliestStart, and width=latestStart-earliestStart.
When to use this tool
Use Fixation Time Precision Gap when you need this specimen-record, sampling, processing-time, dimensional, or uncertainty calculation.
How to use the tool and how it works
- Enter earliestStart, latestStart, endAt. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read minimumDuration, maximumDuration, width. Use the output convention below.
Require earliestStart<=latestStart<=endAt. Return minimumDuration=endAt-latestStart, maximumDuration=endAt-earliestStart, and width=latestStart-earliestStart.1

}Limitations and assumptions
- All time coordinates need one unit and origin. The interval reflects only supplied start-time uncertainty and does not validate actual fixation conditions, a processing protocol, or a clinical acceptance range.
- Inputs must satisfy both the field types and the cross-field conditions above. Invalid input causes an error; a successful false flag or documented placeholder is a different result.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Use validated laboratory procedures, traceable measurements, and authenticated specimen records for a complete assessment. Check the relevant sampling and processing assumptions before interpreting a local quantity.
