110817 SETDTM - Set Date and Time Utilizing Digital Pathways TCU-150 Clock Version: V1.0, November 1985 Submitted by: John C. Gibbons, Macedonia, OH Operating System: RT-11 V4.0 or later Source Language: MACRO-11 Memory Required: 581 Words Hardware Required: Digital Pathways TCU-150 UNIBUS Clock Keywords: Clock Abstract: SETDTM is a program designed to read the Digital Pathways, Inc. TCU-150 battery operated UNIBUS clock and set the system date and time accordingly under the RT-11 V4 or later monitor. The TCU-150 has the hardware capability of providing the Julian year, month and day as well as the hour, minute and second. Leap years are accounted for by the TCU-150 in hardware as well. This program employs a unique feature in that it also provides for an optional Daylight Savings Time (DST) set-ahead (typically in the Spring) by manually setting a storage location (DSTFLG) in this program to a non-zero value. This allows the user to account for the time change WITHOUT resetting the clock registers in the TCU-150 directly. Leap years are also accounted for when there is a month roll-over for the DST calculation. Indirect command files are provided with the distribution to accomplish the task of changing from Standard Time to Daylight Savings Time and vice versa. Constants are also provided in the source listings to accomodate the use of either the 50HZ or 60HZ line frequency clocks. The distribution has both 50HZ and 60HZ versions already compiled for the users convenience.
