"""Simple time utilities Fire CLI.

This example demonstrates exposing simple time helper functions using Fire.
Fire() is called with no target component so all functions in this module
become CLI commands.

Example usage:
  time_tools now
  time_tools to-seconds 1 30
  time_tools add-seconds "2024-01-01 10:00:00" 120
"""

import fire
import datetime


def now():
  """Return the current datetime as a string."""
  return datetime.datetime.now().strftime("%Y-%m-%d %H:%M:%S")


def to_seconds(minutes=0, seconds=0):
  """Return minutes + seconds converted to total seconds."""
  return minutes * 60 + seconds


def add_seconds(time_string="", seconds=0):
  """Add seconds to a datetime string."""
  dt = datetime.datetime.strptime(time_string, "%Y-%m-%d %H:%M:%S")
  new_dt = dt + datetime.timedelta(seconds=seconds)
  return new_dt.strftime("%Y-%m-%d %H:%M:%S")
