Procedure DateTimeToString(out Result: const FormatStr: const DateTime: TDateTime) Free pascal convert timestamp to date code#When the above code was compiled and executed, it produced following result: Date and Time at the time of writing : 18:51:įree Pascal provides a simple time stamp structure named TTimeStamp, which has the following format: type TTimeStamp = recordįree Pascal provides the following date and time functions: S.Nįunction DateTimeToFileDate(DateTime: TDateTime):LongInt įunction DateTimeToStr( DateTime: TDateTime): Ĭonstruct string representation of DateTimeįunction DateTimeToStr(DateTime: TDateTime const FormatSettings: TFormatSettings): The Now function returns the current date and time: Program DatenTimeDemo uses sysutils begin writeln ( 'Date and Time at the time of writing : ', DateTimeToStr (Now ) ) end. When the above code was compiled and executed, it produced following result: Date: 4.195700000000000E+004 YY ,MM ,DD : Word begin writeln ( 'Date : ' ,Date ) DeCodeDate (Date ,YY ,MM ,DD ) writeln ( format ( 'Today is (DD/MM/YY): %d/%d/%d ', ) ) Free pascal convert timestamp to date how to#The following program demonstrates how to use it in your program to display the current date: Program DateDemo uses sysutils var The TDateTime is a double value, which needs some decoding and formatting. The Date function returns the current date in TDateTime format. When the above code was compiled and executed, it produced following result: Current time : 18:33:08 The following example shows how to get the current time: program TimeDemo uses sysutils begin writeln ( 'Current time : ', TimeToStr (Time ) ) end. Pascal's TimeToString function gives you the current time in a colon(: ) delimited form. However, the actual name and workings of these functions are different for different compilers. Pascal also provides powerful tools for date arithmetic that makes manipulating dates easy. Dates are so much part of everyday life that it becomes easy to work with them without thinking. Free pascal convert timestamp to date software#These constants are set according to the internationalizationMost of the software you write needs implementing some form of date functions returning current date and time. For the Win32 version of the sysutils unit, The following constants control the formatting of currenciesĪnd numbers. The following constants control the formatting of times. ('Sunday','Monday','Tuesday','Wednesday', 'September','October','November','December') LongDateFormat: string = 'dd" "mmmm" "yyyy' Settings of Windows by the initialization code of the unit. The following constants control the formatting of dates.įor the Win32 version of the sysutils unit, theseĬonstants are set according to the internationalization Versions, this information is obtained from the operating system. The initialization code of the sysutils unit fills these The following variables are used in the case translation routines. The following constants can be used in the FileSeek call. The following constants can be used in the FileOpen call. The following constants are file-attributes that need to be matched in the If code is to be portable, that part shouldn't The following type is used in the FindFirst, FindNextĪnd FindClose functions. The following types are used frequently in date and time functions. SecsPerDay = 24 * 60 * 60 // Seconds and milliseconds per dayĭateDelta = 693594 // Days between and The following general-purpose constants are defined: The use and meaning of these types should be clear, so no extra information Tintegerset = set of 0.sizeof(integer)*8-1 The following general-purpose types are defined: That are defined, followed by an overview of functions grouped byįunctionality, and lastly the complete explanation of each function. This chapter starts out with a definition of all types and constants With the latter, it is designed to work on multiple platforms. It aims to be compatible to the Delphi sysutils unit, but in contrast Was largely written by Gertjan Schouten, and completed by Michael Van Canneyt. This chapter describes the sysutils unit.
