Description
Form offsetAtAnchor+driftPerTime × (recordedTime-anchorTime) for correction and subtract it from recordedTime.
Weather observation clocks and accumulation intervals can have offsets, drift, or resets. Correcting a supplied clock model differs from inferring an actual missing observation or synchronization history.
Form offsetAtAnchor+driftPerTime × (recordedTime-anchorTime) for correction and subtract it from recordedTime.
When to use this tool
Use Rainfall Gauge Clock Drift Adjustment when you need one explicit observation-time comparison or correction.
How to use the tool and how it works
- Enter recordedTime, anchorTime, offsetAtAnchor, driftPerTime. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read correction, correctedTime. Use the output convention below.

}Limitations and assumptions
- Times and offsets share units and driftPerTime is correction units per time unit; this linear clock model does not infer drift, timezone, or actual synchronization.
- 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.
