http://gerrit.cloudera.org:8080/#/c/6936/1/be/src/runtime/timestamp-value.h
File be/src/runtime/timestamp-value.h:

Line 108:   static TimestampValue FromUnixTimeMicros(int64_t unix_time_micros);
I'm confused as to why it no longer takes two parameters (maybe its just that the comment
needs to be updated?)


http://gerrit.cloudera.org:8080/#/c/6936/1/be/src/runtime/timestamp-value.inline.h
File be/src/runtime/timestamp-value.inline.h:

Line 32:   int64_t ts_seconds = unix_time_micros / MICROS_PER_SEC;
I don't understand what this is supposed to be doing - it looks like you're just separating
'unix_time_micros' into two parts and then adding them back together again.

PS1, Line 125:  value
extraneous word?

Line 253:                          ts2 timestamp default cast('00:00:00' as timestamp))
I guess the intention here is that this will fail? Is there an error we can catch?
