Expiration Dates 追蹤
I am struggling with the enclosed label and would like some help.
Essentially, there are 3 places where a date is required.
There is a production date as Julian date (shown on the label as 233 so this is achieved using jjj in the format).
There is also a use by date shown as 03/09/15 (UK format) which has an offset of x days
There is the same use by date on the barcode shown as 150903
What I am finding is that if I link the production date with the use by date, the offset will affect both.
I would like to use the production date as the date to enter when printing a label and the 2 other dates to calculate themselves
Does anyone have any suggestions? I'm sure it's a simple challenge but I have tried different ways without success.
