(1) Item: Time Stamp Block
The date format of Time Stamp Block is MON Sep 23 14:43:52 1992. Note that the year is in a four-
digit format.
(2) Item: Timer Clock Block
For Time of Date or Elapsed Time (both cyclic and non-cyclic), the block output is based on the
seconds elapsed since midnight (i.e., 00:00:00) January 1, 1970 Universal Coordinated Time.
(3) Item: Alarm Log Block
If the Alarm Message Format: Date (MM/DD/YYYY) option is checked, the date message for the alarm
will be stored in the ADAMView.ELF file in MM/DD/YYYY format, where YYYY represents the year.
It is a four-digit year format, and thus Y2K compliant. This file is used in the Report Designer for a listing
report.
(4) Item: Historical Trend Block
This stores one file per day in binary format and the filename is YYMMDDXX.HST, where YY represents
the year. For example, if it is 1998, then YY = 98. For the year 2001, YY = 01. If your system is
running from December 31, 1999 to January 1, 2000, ADAMView will store the historical data into two
binary files: one is 99123101.HST and the other is 00000101.HST.
You can search back and forth to view the data on December 31, 1999 and January 1. 2000. It dis-
plays the date as month/day/year, where the year is in a four-digit format.
In addition, the HIST Conversion under the File menu can accept a four-digit year in the Start Date and
End Date fields for the conversion range. ADAMView can retrieve the right historical binary file (*.HST)
and convert it to an ASCII file (*.TXT).
(5) Item: Log File Block
For the Open method: "Open at n minutes from midnight" under Advanced Option, the file will be
opened according to the day which is independent of the year.
(6) Item: Runtime Error Message File: RUNERR.LOG
The date format is MM/DD/YY HH:MM:SS. Although the year is stored in two-digit format, this is only
for storage purposes.
(7) Item: Basic Script Commands
The date-related commands (i.e., Date and Year) both accept and output 4-digit years.
(8) Item: Report Designer
For the formatted report, i.e., Monthly/Yearly reports, the database filename is MNYYYYMM.DBF
where YYYY represents the year. It is in a four-digit format.
For the listing report, i.e., Alarm/Control report, it will retrieve the correct data for the report date which
accepts a four-digit year format.
The date-related commands: $DATE outputs four-digit year format like MM-DD-YYYY.
