[Grammar] Where or When?

[Flogger]

Hello,

The following sentence is a line of lyrics extracted from the song of Unchain Utopia. I want to know if it is grammatical to use "where" in this sentence. I think because of speaking about time it is more appropriate to use "when".

We're in a time where all enterprises fall

Regards,

Where can apply to time as well as location or situation.
