BloombergLP::ball::ObserverFormatterImp::ObserverFormatterImp

Create a ObserverFormatterImp instance that formats log records using the specified format and timezoneDefault. It is strongly advised to specify UTC for timezoneDefault. Optionally specify an allocator (e.g., the address of a bslma::Allocator object) to supply memory; otherwise, the default allocator is used. The behavior is undefined unless format is a valid format string (either one that starts with a scheme or a "text" scheme format). Note that not giving a valid default format string by the observer will result in no logging output if no valid format is set afterwards, so it is a serious error.
