test_time_conversions module
Test timing conversions between reference frames.
- test_time_conversions.leapseconds_table()[source]
Table with reference for when leapseconds were added
- Returns:
leapseconds_ref_table – Array of reference times and leap seconds for validation
- Return type:
np.ndarray
- test_time_conversions.test_datetime_to_gps_millis()[source]
Test UTC datetime to milliseconds since GPS epoch conversion and back
Datetime to GPS milliseconds conversion was obtained using an online convertor [7].
References
- test_time_conversions.test_datetime_to_tow()[source]
Test that datetime conversion to GPS or UTC secs does not fail.
Verified by using an online gps time calculator [1].

- test_time_conversions.test_datetime_to_unix_millis()[source]
Test UTC datetime to milliseconds since UNIX epoch conversion and back
Datetime to UNIX milliseconds conversion was obtained using an online convertor [6].
References
- test_time_conversions.test_get_leap_seconds(check_leapseconds)[source]
Test to validate leap seconds based on input time.
- Parameters:
check_leapseconds (np.ndarray) – Array of times at which leap seconds changed and changed values
- test_time_conversions.test_gps_datetime_to_gps_millis()[source]
Test conversion of GPS datetime to GPS millis.
- test_time_conversions.test_gps_unix_millis()[source]
Test milliseconds since GPS epoch to milliseconds since UNIX epoch.
Given UTC time, milliseconds since the UNIX epoch were calculated from an online calculator [8]. The UTC time was converted to seconds (and hence milliseconds) since GPS epoch using another online calculator [9].
References
- test_time_conversions.test_gps_unix_millis_vect()[source]
Test vectorized version of unix_to_gps_millis and gps_to_unix_millis.
Notes
Test based on the test implemented in test_gps_unix_millis
- test_time_conversions.test_millis_since_gps_epoch_to_tow()[source]
Test milliseconds since gps epoch to time of week.
Test that conversion from milliseconds since GPS epoch to GPS or UTC seconds of the week does not fail.
Given a UTC time epoch, an online GPS Time converter [2] provides seconds since GPS epoch while a GPS Time calculator [3] gives GPS seconds of the week.
References
- test_time_conversions.test_tow_to_unix_millis()[source]
Test TOW to milliseconds since Unix epoch and back.
Given UTC time, milli seconds since the UNIX epoch were calculated from an online calculator [4]. The UTC time was converted to GPS time and TOW using another online calculator [5].

Checking internal timezone conversions to UTC
Checks that when timezone information is None or attribute doesn’t exist, the timezone is changed to UTC. Also checks that if time is in non-UTC frame of reference, the time is converted to UTC before being returned.
