The format of the output is determined by the sizefmt version of the config command. The flastmod command inserts the last modified date of the indicated file into the HTML data stream. The format of the output is determined by the timefmt version of the config command. The tag and value, if present in the command, define a condition that must be true for the command to be effected. If the condition fails, the command has no effect.
All conditions take the form of a fixed-length string comparison.
The comparison is always case insensitive. The longer the value string, the more restrictive your condition. The before, after, and during tags restrict the show or hide command to work only before, after, or during specific dates and times. The below, above, and exact tags restrict the show or hide command to work only when an internally generated random integer is below, above, or exactly the same as the supplied value. The random integer is generated once for each SSI file processed by the plug-in.
