TTL discrepency between redis and garnet

[sspeaks]

Describe the bug

When executing the TTL command for a particular keys, redis and garnet differ.

Redis rounds the number of seconds to the nearest integer.
Garnet floors the number of seconds.

Not sure that such a discrepancy really matters or if y'all care about those kinda things, but I figured I'd mention.

Steps to reproduce the bug

Using a script, run the following commands against redis and then against garnet and notice the different output.

set key value
expire key 10
ttl key

Output will be 10 for redis and 9 for garnet.

Expected behavior

Garnet and Redis should both output 10
