## Name
-LogHiresTimestamp — enable microsecond resolution for log timestamps
+log_hires_timestamp — enable microsecond resolution for log timestamps
## Synopsis
-`LogHiresTimestamp = true`
+`log_hires_timestamp = true`
## Description
-When `LogHiresTimestamp` is set to `true`, Momentum writes log timestamps with microsecond (1 µs) resolution instead of the default 1-second resolution.
+When `log_hires_timestamp` is set to `true`, Momentum writes log timestamps with microsecond (1 µs) resolution instead of the default 1-second resolution.
### Rationale
@@ -48,7 +48,7 @@ The effect on each timestamp depends on how it is rendered:
* **Formatted (`strftime`) timestamps.** Timestamps rendered through a `strftime(3)` format string — such as the `timestamp_format` of [chunk_logger](/momentum/4/modules/chunk-logger), the `%t{...}` macro of [custom_logger](/momentum/4/modules/custom-logger), or [timestampformat](/momentum/4/config/ref-timestampformat) — keep the configured format, but every `%S` or `%T` conversion is followed by a `.NNNNNN` six-digit microsecond fraction. For example, the default `[%a %d %b %Y %H:%M:%S] ` becomes `[%a %d %b %Y %H:%M:%S.NNNNNN] ` and renders as `[Mon 20 May 2026 14:32:17.482915] `.
-When `LogHiresTimestamp` is `false` (the default), timestamps are emitted exactly as in previous releases of Momentum, with 1-second resolution and no `.NNNNNN` fraction.
