Subject: Switch to unsigned values for the timestamp query results.
X-Git-Url: https://git.cworth.org/git?p=fips;a=commitdiff_plain;h=b158889b37077e5700b3323fe5f6dd57a38548f6

Switch to unsigned values for the timestamp query results.

Since these are timestamps they can't be negative, so an unsigned
value makes sense.
