Usage¶

Import¶

The module can be imported as:

Import

from gnss_calendar.gnss_calendar import GnssCalendar

Initialize¶

You can initialize a gnss-calender object as:

Initialize with string

obj = GnssCalendar(epoch_str=<epoch_string>)

if not obj.epoch:
    return None

Alternatively, you can pass an already initialized datetime object to the epoch parameter.

Initialize with datetime object

import datetime as dt

epoch = dt.datetime(2022, 1, 1, 12, 0, 0)
obj = GnssCalendar(epoch=epoch)

Console Application¶

The application ships also with a terminal client application named gnss_calendar_cli.py:

python gnss_calendar_cli.py 2022-01-01

Note

If passed without any arguments, the current datetime in UTC will be used.

The result is as follows:
