Error message

时间格式无效

What it means

OtherUtil.ParseSeconds is a validation helper that parses CLI time-span strings like '1h3m20s' into total seconds using a regex. It throws this ArgumentException when the input string does not match the expected <number><h|m|s> unit pattern at all — i.e. the user passed a malformed value to an option that expects a duration (e.g. --live-real-time-deletion or similar time arguments).

Solutions

1. Write the duration using the accepted unit syntax, e.g. 30s, 5m, 2h, or combined like 1h3m20s
2. Do not use other formats such as '00:30:00', '30' without a unit suffix, or '30sec'
3. Check for stray spaces or non-ASCII characters copied into the argument

Example fix

Replace --live-record-limit 01:00:00 with --live-record-limit 1h (or 1h30m / 90m as needed).

When it happens

Trigger: A command-line time argument (e.g. live buffer/record durations) does not match the TimeStrRegex pattern like ^(\d+h)?(\d+m)?(\d+s)?$ — missing units, wrong separators, or a totally different duration format.

Common situations: Users habitually type HH:mm:ss style durations, plain numbers without unit suffixes, or values with spaces such as '1h 3m' which the regex cannot match.
