72 --------------

74 Messages in the archive will expire after some time, by default one
75 week. This can be changed by setting `archive_expires_after`:
76
77 ``` {.lua}
78 archive_expires_after = "1d" -- one day
79
80 archive_expires_after = "1w" -- one week, the default
81
82 archive_expires_after = "2m" -- two months
83
84 archive_expires_after = "1y" -- one year
85
86 archive_expires_after = 60 * 60 -- one hour
87
88 archive_expires_after = "never" -- forever
89 ```

91 The format is an integer number of seconds or a multiple of a period
92 given by a suffix that can be one of `d` (day), `w` (week), `m` (month)
93 or `y` (year). No multiplier means seconds.
