Date & Period	Find first/last date of period, period iteration
Timezone	Convert local to UTC, UTC to local
Barcode	Check barcode exists, generate EAN13
Batch Processing	Split large recordsets into batches
after_commit	Execute code after transaction commit
Vietnamese Text	Strip accents, convert to non-accent
File Utilities	Zip directories, get file size
Number Utilities	Round to decimal places

DTGBase Abstract Model

Inherit from DTGBase

Location:

addons_customs/erp/dtg_base/models/dtg_base.py

python

from odoo import models

class MyModel(models.Model):
    _name = 'my.model'
    _inherit = ['dtg_base.dtg_base']

    def my_method(self):
        # Now you have access to all DTGBase utilities
        first_date = self.find_first_date_of_period('2024-01-15', 'month')
        utc_date = self.convert_local_to_utc('2024-01-15 10:00:00')
