Description
Return localEnd-localStart, endOffset-startOffset, and local duration minus offset change as elapsedMinutes.
Personal health logs distinguish clock coordinates, elapsed durations, pauses, and missing time metadata. A supplied time comparison organizes records without measuring an activity or assessing its health effects.
Return localEnd-localStart, endOffset-startOffset, and local duration minus offset change as elapsedMinutes.
When to use this tool
Use Sleep Entry Clock Reference Pair when you need one explicit diary-duration or clock-accounting component.
How to use the tool and how it works
- Enter localStart, localEnd, startOffset, endOffset. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read localMinutes, elapsedMinutes, offsetChange. Use the output convention below.
Require startOffset and endOffset within -1439 to 1439 minutes. Return localEnd-localStart, endOffset-startOffset, and local duration minus offset change as elapsedMinutes.1
| Input field | Meaning and units | Accepted input |
|---|---|---|
| localStart | Local Start | Required. Safe integer. |
| localEnd | Local End | Required. Safe integer. |
| startOffset | Start local-minus-reference offset in minutes. | Required. Safe integer; minimum -1439; maximum 1439. |
| endOffset | End local-minus-reference offset in minutes. | Required. Safe integer; minimum -1439; maximum 1439. |
| Output field | Interpretation | Returned shape |
|---|---|---|
| localMinutes | Local Minutes | Required. Safe integer. |
| elapsedMinutes | Elapsed Minutes | Required. Safe integer. |
| offsetChange | Offset Change | Required. Safe integer. |

}Limitations and assumptions
- Offsets use local-minus-reference convention and local endpoints share a continuous minute coordinate; no timezone or daylight-saving rule is inferred and signed durations are retained.
- 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. Numeric signed-zero results are exported as zero.
Alternative or Complementary methods
Retain dates and offset information and consult an appropriate professional for questions about health, care, or suitable activity.
