Review comment:
The description for the supported special values in this pr should be;
```
epoch [zoneid] - 1970-01-01 00:00:00+00 (Unix system time zero)
today [zoneid] - midnight today.
yesterday [zoneid] -midnight yesterday
tomorrow [zoneid] - midnight tomorrow
now - current query start time.
```
