Syntax of Clock Codes

The {date} substitution variable lets you specify an optional clock code so you can specify the format of the date. Some other substitution variables such as {asOfDate} also support clock codes. Some script parameters also support clock codes.

The syntax of clock codes is % followed by a letter. For example, %Y shows the year as 4-digits. You can use more than one %LETTER code, such as %b/%d/%Y to show the month/day/year. Characters that do not have a preceding % are copied as-is to the result.

Example	Example Result
`{date Today is %b %d %Y}`	`Today is Jun 27 2003`
`{date %I:%M %p}`	`10:32 PM`

Script Parameters Supported

The following script parameters can contain clock codes.

Script Parameter	Example	Example Result	Example Meaning
`asinsearch`	`asinsearch=week%W`	`asinsearch=week23`	Use this week's week number as the value of the `asinsearch` parameter. In this example, the file `week23.txt` (if it exists) is read for a list of ASIN's. Thus you could automatically display a different list of products each week.
`exclude`	`exclude=%b`	`exclude=jun`	Use this month's abbreviated name (Jan, Feb, ..., Dec) as the value of the `exclude` parameter. Thus a different exclude file will be selected each month.
`format`	`format=%a`	`format=fri`	Use today's abbreviated date (Sun, Mon, ..., Sat) as the value of the `format` parameter. Thus a different format file will be selected each day.
`template`	`template=page%q`	`template=page2`	Use this quarter's number as part of the value of the `template` parameter. Thus a different template file is selected for each quarter of the year.
`upcsearch`	`upcsearch=week%W`	`upcsearch=week23`	Use this week's week number as the value of the `upcsearch` parameter. In this example, the file `week23.txt` (if it exists) is read for a list of UPC's. Thus you could automatically display a different list of products each week.
