Python Code for Converting Julian Day to UTC Standard Time

The following is a brief description of the Python code for converting Julian day to UTC standard time in datetime64 format, using the decimal_to_sexagesimal and decimal_to_time modules:

Module decimal_to_sexagesimal: Convert decimal time to actual minutes

def decimal_to_sexagesimal(decimal_time):
    """
    Converts decimal time to actual minutes

    Parameters:
    decimal_time (float): Decimal time in hours

    Returns:
    int: Minutes after conversion
    """
    minutes = round((decimal_time % 1) * 60)
    return minutes

This module takes in a decimal time in hours and converts it to actual minutes.

Module decimal_to_time: Convert decimal time to actual time main function

def decimal_to_time(decimal_time):
    """
    Converts decimal time to actual time

    Parameters:
    decimal_time (float): Decimal time in hours

    Returns:
    str: Actual time in HH:MM format
    """
    hours = int(decimal_time)
    minutes = decimal_to_sexagesimal(decimal_time)
    time_str = f"{hours:02d}:{minutes:02d}"
    return time_str

This module takes in a decimal time in hours and converts it to actual time in HH:MM format using the decimal_to_sexagesimal module.

Module juliandate_to_utc: Convert julian day to actual date time 64 format

import numpy as np

def juliandate_to_utc(jd):
    """
    Converts julian day to UTC datetime64 format

    Parameters:
    jd (float): Julian day

    Returns:
    np.datetime64: UTC datetime64 format
    """
    j2000 = np.datetime64("2000-01-01T12:00:00")
    days_since_j2000 = jd - 2451545.0
    seconds_since_j2000 = days_since_j2000 * 86400
    dt = j2000 + np.timedelta64(int(seconds_since_j2000), "s")
    return dt

This module takes in a Julian day and converts it to UTC datetime64 format using the J2000 epoch. It returns the datetime64 object.

Technical notes:

• These modules are intended for use in Python 3.x and may not be compatible with earlier versions.
• The code may require additional libraries or dependencies to run, such as NumPy.
• The decimal_to_sexagesimal module assumes a 24-hour clock format and may require modification to support other formats.
• The juliandate_to_utc module assumes a Gregorian calendar and may require modification to support other calendars.
• The code should be thoroughly tested and validated before being used in any critical applications, and any errors or bugs should be addressed before deployment.
