The meaning of the sentence is straightforward. The only odd thing about the sentence is the use of the determiner "this". It is odd because there is only one today, so why would one need to specify it with a determiner. All of these sound odd but are not wrong:
"our todays"
"these todays"
"some today"
"any today"
"no today", etc.
All of these are odd, but not wrong. They sound poetic.
