Sample Collection Date Range
From the help published with Drinking Water Watch 3.5, reproduced as delivered.
The Sample Collection Date Range fields let you further broaden or constrain the number of sample results your criteria retrieves. To prevent lengthy accidental searches, the sample search default will always return results for the most recent two years unless you explicitly enter a wider or narrower date range. If you remove the default dates, the search still uses the most recent two years as search criteria. To return results from more than two years ago, you need to enter a “from” date that is before two years ago. For example, if today’s date is June 9, 2005,
to find samples from the last 5 years, you would need to enter 6/9/2000 in the “from” date and 6/9/2005 in the “to” date of the search date range. To find samples from the last month.
to find samples from the last month, you would need to enter 5/10/2005 in the “from” date and 6/9/2005 in the “to” date of the search date range. To find samples from the last month.
