## Public Disclosure Timing ## Public Disclosure Timing
A public disclosure date is negotiated by the ClickHouse maintainers and the bug submitter. We prefer to fully disclose the bug as soon as possible once a user mitigation is available. It is reasonable to delay disclosure when the bug or the fix is not yet fully understood, the solution is not well-tested, or for vendor coordination. The timeframe for disclosure is from immediate (especially if it's already publicly known) to 90 days. For a vulnerability with a straightforward mitigation, we expect report date to disclosure date to be on the order of 7 days.

## parseDateTimeBestEffortUS ## parseDateTimeBestEffortUS
This function is similar to [parseDateTimeBestEffort](#parsedatetimebesteffort), the only difference is that this function prefers US date format (`MM/DD/YYYY` etc.) in case of ambiguity. This function behaves like [parseDateTimeBestEffort](#parsedatetimebesteffort) for ISO date formats, e.g. `YYYY-MM-DD hh:mm:ss`, and other date formats where the month and date components can be unambiguously extracted, e.g. `YYYYMMDDhhmmss`, `YYYY-MM`, `DD hh`, or `YYYY-MM-DD hh:mm:ss ±h:mm`. If the month and the date components cannot be unambiguously extracted, e.g. `MM/DD/YYYY`, `MM-DD-YYYY`, or `MM-DD-YY`, it prefers the US date format instead of `DD/MM/YYYY`, `DD-MM-YYYY`, or `DD-MM-YY`. As an exception from the latter, if the month is bigger than 12 and smaller or equal than 31, this function falls back to the behavior of [parseDateTimeBestEffort](#parsedatetimebesteffort), e.g. `15/08/2020` is parsed as `2020-08-15`.
**Syntax**
``` sql
parseDateTimeBestEffortUS(time_string [, time_zone])
```
**Arguments**
- `time_string` — String containing a date and time to convert. [String](../../sql-reference/data-types/string.md).
- `time_zone` — Time zone. The function parses `time_string` according to the time zone. [String](../../sql-reference/data-types/string.md).
**Supported non-standard formats**
- A string containing 9..10 digit [unix timestamp](https://en.wikipedia.org/wiki/Unix_time).
- A string with a date and a time component: `YYYYMMDDhhmmss`, `MM/DD/YYYY hh:mm:ss`, `MM-DD-YY hh:mm`, `YYYY-MM-DD hh:mm:ss`, etc.
- A string with a date, but no time component: `YYYY`, `YYYYMM`, `YYYY*MM`, `MM/DD/YYYY`, `MM-DD-YY` etc.
- A string with a day and time: `DD`, `DD hh`, `DD hh:mm`. In this case, `YYYY-MM` are substituted as `2000-01`.
- A string that includes the date and time along with time zone offset information: `YYYY-MM-DD hh:mm:ss ±h:mm`, etc. For example, `2020-12-12 17:36:00 -5:00`.
**Returned value**
- `time_string` converted to the `DateTime` data type.
