TIME CODES and SPREADSHEETS ADDENDUM
Lets say you wanted to generate a spreadsheet using Aware Electronics data and
a spreadsheet program, such as Lotus 123 (or Quattro-Pro, etc.).
First convert your Aware data file to an ASCII file and include the date-time
code of "Seconds Since 1/1/70".
Next import this ASCII data file into Lotus (Tools, Import ASCII File, Comma
Delimited).
The seconds since 1/1/70 00:00:00 is based on east coast time. For example a
data-time of July 14, 1994 11:31:26 is equal to 774203486. To convert this
number into Lotus-Quattro-Pro time-date serial number, subtract 18000 then divide
by 86400 then add 25569.
You can perform the above arithmetic using Lotus 123. Lets say you imported a
file into Lotus, as above, with three data points, each one minute apart. If the
first point’s date-time was July 14, 1994 11:31:26, the imported file would
appear in the spreadsheet as follows:
A B C
1 15 774203486
2 18 774203546
3 22 774203606
Cell A1 contains the value of the first data point and cell B1 contains the time
code. If you wanted to generate a Lotus style Date-Time serial number in cell
C1, you could place the following code in cell C1:
((B1-18000)/86400)+25569
You could then copy C1 to the block of cells C2-C3. When you do this, Lotus will
automatically increment the B1 cell reference. The result would look like this:
A B C
1 15 774203486 34529.480162037
2 18 774203546 34529.480856481
3 22 774203606 34529.481550926
Now you could change the Numeric Format of the C column to a Date format and/or
a Time format. You could then assign the C column to the X-axis in a graph (with
the A column assigned to the Y-axis).
(Note: To save memory in your spreadsheet, you could convert the formulas in the
C column block to their resulting values, or write a macro that would do all of
the above, one row at a time).
(Also Note: When making graphs with a spreadsheet program, you may want to
change the font size of the x-axis tick labels, and/or instruct the spreadsheet
to use minor x-axis tick labels in conjunction with major tick labels, thereby
providing more room for the x-axis date labels)
(Also Note: The Aware programs are written in Borland’s Turbo C. Turbo C
functions default to EST time zone (18000 seconds behind GMT). Turbo C library
routines cancel out the time zone parameter, so all Date-Time representations
within the Aware programs will display Dates and Times based on the time set in
the computer, without regard to time zone or DST, but this is the reason why we
subtract 18000, in the above formula, from the time code, for use within the
spreadsheet).
