ALT text for colored icons

[Tracy Di Marco White <gendalia (at) iastate.edu>]

The ALT text for the various icons to notify us of problems show
"sslcert:yellow:4.47 days" and "sslcert:yellow:acked:4.47 days".
Would it be reasonable to change it to
"sslcert:yellow:4.47 days:acked:2 hours"
or something like that, so it's more obvious that yellow & acked
aren't both the same time period?  Or is that loading too much
into an ALT tag?
