Hi!
 
I looked trhough the patchset.
 
I also compiled the bracnch and tested by hand.
 
Example:
 
tarantool> datetime = require('datetime')
---
...
tarantool> datetime.new('2020-01-02 02:00')
---
- 1970-01-01T00:00Z
...
tarantool> datetime.new('2020-01-02 02:00+0300')
---
- 1970-01-01T00:00Z
...
tarantool> datetime.new('2020-01-02 02:00:11+0300')
---
- 1970-01-01T00:00Z
...
tarantool> datetime.new('2020-01-02T02:00:11+0300')
---
- 1970-01-01T00:00Z
...
 
 
The code looks like as broken.
 
Also my notes:
 
*  tostring has to return datetime string with seconds and timezone
*  also the other databases try to avoid to use «Z» symbol in datetime-format, so I thing we should use «+00:00» instead «Z»
 
Yesterday we approved the following API:
 
T:add{year=XXX, month=YYY, ...}
T:sub{year=XXX, month=YYY, ...}
T:set{year=XXX, …, tz=’+03:00’}
T:strftime(‘%F %D %z’)
 
I want to see a test set for the API.

Also we approved the following methods:
  T:sec() — 35
T:min() — 12
T:day() — 19
T:wday() — 5
T:yday() — 231
T:year() — 2021
T:month() — 8
T:hour() — 23
T:tz() — ‘+03:00’
 
It would be nice to see test set for each of the functions.
 
Also it would be nice to rename ambigouos items «secs» to «epoch» or «timestamp»
Datetime object must have methods to return integer and float timestamp:
 
T:epoch()
T:timestamp()
