F2897 (7)
Displayed as “f” in the display field.
The
<F2897> function is a special date-coding
for US pipe manufacturers. It is a specific US-
guideline to convert the 5 digit date code
containing the “Julian date” and the last two
digits of the year to a just 3 digits long
calculated alphanumerical number.
F2897 is code that shows the current
Julian date and the last 2 digits of the
current year as a 3 digit alphanumerical
expression.
Julian date (12)
Displayed as “j” in the display field.
The
<Julian> function shows the day-of-year
number for the current date.
The 25 th February is the 56 th day of the
year 2014.
How to set ab expiry date
The expiry date is created by an offset on the current date/time. It is possible to
choose either days or months for the offset.
Expiry date – calculated
on
the basis of days
If the expiry date is calculated in days the result will show the current day or/and
time plus the offset. The function will consider the actual number of days of the
current month as well as leap years.
Expiry date – calculated on the basis of months
If months are used for the calculation of the expiry date, the following rules are
valid:
If the specific day code does not exist in the month which would be the “expiry
month”, the expiry date will be shifted into the next month. The number of days
the expiry date would be shifted depends on the “missing” days in the month in
which the expiry date originally would have been. Please see the examples for
details.
Example 1:
The day of the production is: 31 August 2012
The expiry date shell be: 6 months
The regular result of the final date would be: 31. February 2013. Due to the fact
that this day not exists, the printer will print: 03. March 2013. In that case 3 days
are missing in February.
