zfs rename <old_snapshot> <new_snapshot>

# zfs list -t snapshot
NAME                            USED  AVAIL  REFER  MOUNTPOINT
test_pool/fs1/data@090610          0      -    18K  -

# zfs rename test_pool/fs1/data@090610 test_pool/fs1/data@09jun10

or

# zfs rename test_pool/fs1/data@090610 09jun10

# zfs list -t snapshot
test_pool/fs1/data@09jun10         0      -    18K  -

To rename dependent, use the "-r" option:

# zfs rename -r test_pool/fs1@090610 test_pool/fs1@09jun10
