Important Notice

The pages on this site contain documentation for very old MS-DOS software, purely for historical purposes. If you're looking for up-to-date documentation, particularly for programming, you should not rely on the information found here, as it will be woefully out of date.

TimeSerial# returns a serial number that represents the time of the
arguments.
 
TimeSerial# (hour%, minute%, second%)
    ■ You can use negative numbers as arguments, as long as the resulting
      serial number is positive. For example, to find the serial number
      for the time 50 seconds before 2:00:02, you could use:
        TimeSerial#(2,0,2-50)
 
Usage Notes
    ■ For information on serial numbers, see ◄Serial Numbers►.
 
Important
    ■ To use TimeSerial# in the QBX environment, use the FINANCER.QLB Quick
      library. To use TimeSerial# outside the QBX environment, link your
      program with the appropriate DTFMTxx.LIB file. Depending on the
      compiler options you chose when you installed BASIC, one or more of
      the following files will be available:
 
           Filename         Compiler options
           ════════════     ═════════════════════════════════════════════
           DTFMTER.LIB      80x87 or emulator math; DOS or OS/2 real mode
           DTFMTAR.LIB      Alternate math; DOS or OS/2 real mode
           DTFMTEP.LIB      80x87 or emulator math, OS/2 protected mode
           DTFMTAP.LIB      Alternate math; OS/2 protected mode
 
    ■ The DATIM.BI header file contains the necessary declarations for
      using TimeSerial#.
    ■ For more information on using libraries, see "Creating and Using
      Quick Libraries" and "Using LINK and LIB" in the BASIC Programmer's
      Guide.
