Description
Converts a string to a TDateTime value.
Call StrToTime to parse a string that specifies a time value. If S does not contain a valid time, StrToTime raises an EConvertError exception.
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 A.M. or P.M. indicator. The numbers represent hour, minute, and (optionally) second, in that order. If the time is followed by A.M. or P.M., it is assumed to be in 12-hour clock format. If no A.M. or P.M. indicator is included, the time is assumed to be in 24-hour clock format.
The first form of StrToTime is not thread-safe, because it uses localization information contained in global variables. The second form of StrToTime, which is thread-safe, refers to localization information contained in the AFormatSettings parameter. Before calling the thread-safe form of StrToTime, you must populate AFormatSettings with localization information. To populate AFormatSettings with a set of default locale values, call TFormatSettings.Create.
