 ### Encode
 ```python
-<D/T/DT> = D/T/DT.fromisoformat(<str>)      # From 'YYYY-MM-DD', 'HH:MM:SS.ffffff[+<offset>]' or both.
-<DT>     = DT.strptime(<str>, '<format>')   # Datetime from string according to <format>.
+<D/T/DT> = D/T/DT.fromisoformat(<str>)      # From 'YYYY-MM-DD' / 'HH:MM:SS.ffffff[+<offset>]'.
+<DT>     = DT.strptime(<str>, '<format>')   # Datetime from string according to format.
 <D/DTn>  = D/DT.fromordinal(<int>)          # Date or datetime from days since Christ.
-<D/DTn>  = D/DT.fromtimestamp(<real>)       # Date or datetime from seconds since Epoch in local time.
-<DTn>    = DT.utcfromtimestamp(<real>)      # Naive datetime from seconds since Epoch in UTC time.

 ### Decode                         
 ```python
-<str>    = <D/T/DT>.isoformat()             # 'YYYY-MM-DD', 'HH:MM:SS.ffffff[+<offset>]' or both.
-<str>    = <D/T/DT>.strftime('<format>')    # Returns customized string representation.
-<int>    = <D/DT>.toordinal()               # Returns days since Christ ignoring time and timezone.
-<float>  = <DT>.timestamp()                 # Returns seconds since Epoch in local time or tz if set.
+<str>    = <D/T/DT>.isoformat()             # 'YYYY-MM-DD' / 'HH:MM:SS.ffffff[+<offset>]'.
+<str>    = <D/T/DT>.strftime('<format>')    # Customized string representation.
+<int>    = <D/DT>.toordinal()               # Days since Christ, ignoring time and timezone.
+<float>  = <DT>.timestamp()                 # Seconds since Epoch in local time or tz if set.

+time     == 'HH:MM:SS.ffffff[+<offset>]'
+datetime == 'YYYY-MM-DDTHH:MM:SS.ffffff[+<offset>]'
+```
+
+* **Date: `'YYYY-MM-DD'`.**
+* **Time: `'HH:MM:SS.ffffff[+<offset>]'`.**

 ### Format
 ```python
 >>> dt = datetime.strptime('2015-05-14 23:39:00', '%Y-%m-%d %H:%M:%S')
