datetime - How Can I parse and convert Dates & Times? -

i met odoo first time little less month ago, and, dos systems analyst 90's, helping implement small fast growing local manufacturer. largely out of industry last 15 years, i'm not pro, fast learning python, html (some past exper) , java...

i've been through developer docs, developer's cookbook & essentials, , variety of online tutorials (just google come several search word combinations).

i read closed post asking , there's apparently no actual odoo reference...

can please tell me might find 'date/time' parse , conversion functions can access report using 'canned' 'hr.employee' model?

i prefixed 'br/' h2 keep positioned (only shows on first page), subsequent pages obscure col headers behind layout header... obvious , i'm oblivious, how can adjust 'h2' position below 'header' setup 'report.external_layout'??

on qweb rendering can use python libs time, datetime , relativedelta. included in called qweb context used evaluation (python eval) of code in reports. can see in odoo code here.

that means this:

<t t-set="dspdate" t-value="datetime.datetime.strptime(o.name, '%y-%m-%d %h:%m:%s').strftime('%d/%m/%y')" /> 

i prefer parser classes reports define common functions. example: can define function getdate doing parsing or transforming stuff. report code better parser functions:

<t t-set="dspdate" t-value="getdate(o.name)" />
