The cktime utility prompts a user and validates the response. It defines, among other things, a prompt message whose response should be a time, text for help and error messages,
and a default value (which is returned if the user responds with a RETURN). The user response must match the defined format for the time of day.
All messages are limited in length to 70 characters and are formatted automatically. Any white space used in the definition (including NEWLINE) is stripped. The -W option cancels the automatic formatting. When a tilde is placed at the beginning or end of a message definition, the default text is inserted at that point, allowing both custom text and the
default text to be displayed.
If the prompt, help or error message is not defined, the default message (as defined under NOTES) is displayed.
Three visual tool modules are linked to the cktime command. They are errtime (which formats and displays an error message), helptime (which
formats and displays a help message), and valtime (which validates a response). These modules should be used in conjunction with FML objects. In this
instance, the FML object defines the prompt. When format is defined in the errtime and helptime modules, the messages
will describe the expected format.
