DateTime Converter accuracy and testing

This page documents how Calwarden builds trust for this calculator: source notes, regression-style default tests, limitations, assumptions, unit handling, rounding, and visible change history.

Formula source

**Format:** `YYYYMMDDHHMMSS` * **YYYY:** 4-digit Year * **MM:** 2-digit Month * **DD:** 2-digit Day * **HH:** 2-digit Hour (24-hour clock) * **MM:** 2-digit Minute * **SS:** 2-digit Second (Optional)

Test cases

Default input regression check

Generated from the checked-in default inputs and calculate function.

Inputs

Mode: Generate HL7
Date (Gen): 2026-09-24
Time (Gen): 12:00
HL7 Timestamp (Parse): 20231231235959

Expected outputs

Converted Timestamp: 20260924120000

Known limitations

This page documents the checked-in calculator logic and does not certify results for every real-world edge case.
Use the result as a planning estimate unless the calculator page states a stricter purpose.

Assumptions

Generation uses the browser's local date and time inputs and outputs through whole seconds only.
Parsing focuses on the leading date and time digits and does not fully interpret fractional seconds or timezone offsets.
This tool is meant for quick format conversion, not implementation-guide validation for every TS or DTM precision rule.

Unit handling

Mode accepts one of the configured options.
Date (Gen) accepts calendar dates.
Time (Gen) accepts local time values.
HL7 Timestamp (Parse) accepts text values.

Rounding rules

Number displays use up to 2 decimal places in the calculator UI.
