No, grub doesn't have this feature, but some time ago, i write a patch
for grub4dos that implement a similar feature.It add a new command
checktime to test the current daytime:

checktime * * * * *

The five parameters for checktime is the same as in crontab:minute,
hour, day, month and day of week. this command check if the current
daytime is within the range specified by the parameters, and return
true or false accordingly. Combined this with the script support for
grub2, you can perform some operation in a selected time range.

It's relative easy to port this to grub2, anyone interested ?
