result will depend on the character set of your database.)
Conversion from an integer to a character.

A high-performance time library
Chronos is a performance-oriented time library for Haskell, with a
straightforward API. The main differences between this and the
time library are:
- Chronos uses machine integers where possible. This means that
time-related arithmetic should be faster, with the drawback that the
types are incapable of representing times that are very far in the
future or the past (because Chronos provides nanosecond, rather than
picosecond, resolution). For most users, this is not a hindrance.
- Chronos provides ToJSON/FromJSON instances for
serialisation.
- Chronos provides Unbox instances for working with unboxed
vectors.
- Chronos provides Prim instances for working with byte
arrays/primitive arrays.
- Chronos uses normal non-overloaded haskell functions for encoding
and decoding time. It provides attoparsec parsers for both
Text and ByteString. Additionally, Chronos provides
functions for encoding time to Text or ByteString. The
http://hackage.haskell.org/package/time time> library
accomplishes these with the Data.Time.Format module, which uses
UNIX-style datetime format strings. The approach taken by Chronos is
faster and catches more mistakes at compile time, at the cost of being
less expressive.

The
chroot function takes a selector and an inner scraper and
executes the inner scraper as if it were scraping a document that
consists solely of the tags corresponding to the selector.
This function will match only the first set of tags matching the
selector, to match every set of tags, use
chroots.
The
chroots function takes a selector and an inner scraper and
executes the inner scraper as if it were scraping a document that
consists solely of the tags corresponding to the selector. The inner
scraper is executed for each set of tags (possibly nested) matching
the given selector.
