FIX & Financial Timestamp Converter

Q: What is the FIX UTCTIMESTAMP format?

**`YYYYMMDD-HH:MM:SS`** (seconds) or with milliseconds `.sss` — e.g. `20260813-14:30:00.123`. Used by tags 52 (SendingTime) and 60 (TransactTime).

Q: What is the FIX UTCDateOnly format?

**`YYYYMMDD`** (tag 432 ExpireDate etc.) — the date component of the UTCTIMESTAMP family.

Q: What is the EDIFACT date-time format?

A **date group `YYMMDD`** plus a time group `HHMM` in DTM segments (e.g. `2608131430`), or `CCYYMMDD` for the extended form.

Q: What timezone do FIX timestamps use?

**UTC by convention** (the spec requires the local timezone by default, but UTC is the industry norm for trading systems).

Financial messaging uses precise timestamp conventions: FIX protocol `UTCTIMESTAMP` (`20260813-14:30:00.123`), Bloomberg feed times, Reuters RIC timestamps, and EDIFACT date-time groups (UNB/DTM).

This converter renders your date-time in each financial format so you can build FIX messages, debug market data feeds, and validate EDI payloads.

When to Use FIX & Financial Timestamp

FIX engine development

Generate valid `UTCTIMESTAMP` fields (tag 52/60) for FIX 4.x test messages — format is `YYYYMMDD-HH:MM:SS.sss`.

Market data feed debugging

Compare Bloomberg/Reuters feed timestamps with exchange times when auditing latency.

EDI/EDIFACT payloads

Build UNB/DTM segments with correct date-time groups for B2B order exchanges.
