You can configure Zoom to display the date and time for each search result and allow the user to sort their results chronologically (see section 2.3.2 and 2.3.6). This normally uses the last-modified date and time of the file according to the file system. However, this may not be very useful in cases such as dynamically generated web pages (where it would use the date and time of the server-side script as opposed to a date that is related to the content actually displayed).
In these cases, you can specify your own last-modified date and time in the form of a “http-equiv” Meta tag such as the following:
<meta http-equiv="Last-Modified" content="Sat, 07 Apr 2001 00:58:08 GMT">
Note that this is a standard Meta tag and would also be used by other spiders and applications. Note also that the exact syntax for specifying the date and time must be followed.
The expected format for the date value is:
ddd, DD MMM YYYY HH:MM:SS [Timezone]
• | ddd is the first three letters corresponding to the day of the week (eg. “Mon”, “Tue”, …) |
• | DD is the day of the month in numerals |
• | MMM is the first three letters for the name of the month (eg. “Jan”, “Feb”, …) |
• | YYYY is the year in numeral format (eg. 2005) |
• | HH:MM:SS is the time in hours, minutes, and seconds respectively. This must be specified in 24 hour time. |
• | [Timezone] is optional (eg. “GMT”, “GMT-5”). Note that Zoom will not perform any timezone conversions based on this. |
