Converts a string to a TDateTime value with an error default.
Call TryStrToTime to parse a string that specifies a time value. If S does not contain a valid time, TryStrToTime returns false.
The S parameter must consist of two or three numbers, separated by the character defined by the TimeSeparator global variable or its TFormatSettings equivalent, optionally followed by an AM or PM indicator. The numbers represent hour, minute, and (optionally) second, in that order. If the time is followed by AM or PM, it is assumed to be in 12-hour clock format. If no AM or PM indicator is included, the time is assumed to be in 24-hour clock format.
The first form of TryStrToTime is not thread-safe, because it uses localization information contained in global variables. The second form of TryStrToTime, which is thread-safe, refers to localization information contained in the FormatSettings parameter. Before calling the thread-safe form of TryStrToTime, you must populate FormatSettings with localization information. To populate FormatSettings with a set of default locale values, call GetLocaleFormatSettings.
