source of Sanskrit half-;sloka in Hindi piece

[Yuko Yokochi]

Dear Arlo,

>kalaud.r.m;sa sahasraa.ni vi.s.nusti.s.thati mediniim-bhuutalecaa
The text can be corrected to

kalau t.r.m"satsahasraa.ni vi.s.nus ti.s.thati bhuutale (or medinyaam)|

'In Kali period Vi.s.nu stays on earth for thirty thousands years.'

mediniim-bhuutale caa does not fit the "sloka meter.

I cannot find the source of it.
