Time

Time structure is defined as

 

   Year:
      YYYY (eg 1997)
   Year and month:
      YYYY-MM (eg 1997-07)
   Complete date:
      YYYY-MM-DD (eg 1997-07-16)
   Complete date plus hours and minutes:
      YYYY-MM-DDThh:mmTZD (eg 1997-07-16T19:20+01:00)
   Complete date plus hours, minutes and seconds:
      YYYY-MM-DDThh:mm:ssTZD (eg 1997-07-16T19:20:30+01:00)
   Complete date plus hours, minutes, seconds and a decimal fraction of a second
      YYYY-MM-DDThh:mm:ss.sTZD (eg 1997-07-16T19:20:30.45+01:00)

 

where:

 

     YYYY = four-digit year
     MM   = two-digit month (01=January, etc.)
     DD   = two-digit day of month (01 through 31)
     hh   = two digits of hour (00 through 23) (am/pm NOT allowed)
     mm   = two digits of minute (00 through 59)
     ss   = two digits of second (00 through 59)
     s    = one or more digits representing a decimal fraction of a second
     TZD  = time zone designator (Z or +hh:mm or -hh:mm)


DateTime can be formatted by using system defined function - SimpleDateFormat.

Examples:

<DateTime name="Time" format="$SimpleDateFormat(yyyy-MM-dd'T'HH:mm:ss.SSSZ)"/>

<Attribute name="Time" value="Record.Time" format="$SimpleDateFormat(yyyy.MM.dd G 'at' HH:mm:ss z)"/>

<DateTime name="LastLogin" format="$SimpleDateFormat(yyyy-MM-dd':'HH:mm:ss)"/>


Duration

The duration data type is used to specify a time interval.

The time interval is specified in the following form "PnYnMnDTnHnMnS" where:

  • P indicates the period (required)
  • nY indicates the number of years
  • nM indicates the number of months
  • nD indicates the number of days
  • T indicates the start of a time section (required if you are going to specify hours, minutes, or seconds)
  • nH indicates the number of hours
  • nM indicates the number of minutes
  • nS indicates the number of seconds

The following is an example of a duration declaration might look like this:

        <period>P5Y</period>

The example above indicates a period of five years.

Or it might look like this:

         <period>P5Y2M10D</period>

The example above indicates a period of five years, two months, and 10 days.

Or it might look like this:

        <period>P5Y2M10DT15H</period>

The example above indicates a period of five years, two months, 10 days, and 15 hours.

Or it might look like this:

       <period>PT15H</period>

The example above indicates a period of 15 hours.

Negative Duration

To specify a negative duration, enter a minus sign before the P:

        <period>-P10D</period>

The example above indicates a period of minus 10 days. Â
