Abstract

Disclosed is a method to set a personal computer's clock to a host system's one. The method makes use of a 3270 terminal emulation software which runs on the personal computer, and the software's setup information which specifies the host operating system type for file transfer operation between the host and the personal computer.

Date and Time Synchronization Between Host and Personal Computer

      Disclosed is a method to set a personal computer's clock to a
host system's one.  The method makes use of a 3270 terminal emulation
software which runs on the personal computer, and the software's
setup information which specifies the host operating system type for
file transfer operation between the host and the personal computer.

      A host system's clock can be read and displayed on the personal
computer's screen using a command supplied with the host operating
system.  The syntax of the command, and the format of the resultant
display of date and time vary from operating system to operating
system.

      At setup time, most of 3270 terminal emulation software asks
its user to specify the type of the host operating system.  Fig. 1
shows an example of a pull-down menu for specifying the host
operating system type.  In this example, Multiple Virtual
Storage/Time Sharing Option (MVS/TSO) is checked to indicate the host
operating system.  This information was originally necessary for
selecting a correct command format for transferring files between the
host and the personal computer.  This method makes use of this
information to select a correct command syntax to read the host
system's clock, and to select a correct parsing pattern to extract
date and time values from the command response displayed on the
screen.
