+# arttools
+
+This package contains ART-XC data processing tools. The package will be updated with other tools as they are created.
+
+## arttime
+
+At the current moment artools contains only arttime module. The arttime tool allows to calculate artdays and/or mission time based on Moscow time (and UTC) or MJD and convert them to each other. 
+
+Warning: This tool should not be used to precisely convert of onboard time to real time. 	
+
+### To install:
+
+Clone the repo to your computer::
+
+```
+git clone http://heagit.cosmos.ru:3000/kea/arttools arttools/
+```
+
+Enter the repo and install it with:: 
+
+```
+cd <PATH_TO_ARTTOOLS>
+pip intstall .
+```
+
+### To invoke
+
+```
+from arttools import arttime
+```
+
+### To use:
+
+```
+aday = arttime.ArtTime(artday=8000)
+aday.artday 
+aday.missiontime 
+aday.mjd
+aday.datetime_utc
+aday.datetime_msk
+print(aday)
+```
+
+Available arguments:
+
++ artday       - ART-XC days
++ missiontime  - Mission time - onboard ART-XC seconds
++ mjd          - MJD
++ datetime_utc - Date time based on UTC time zone
++ datetime_msk - Date time based on Moscow time zone (UTC+3)
+
+### Usage CLI
+
+```
+$ arttime --artday=8000 
+$ arttime --missiontime=691200000
+$ arttime --mjd=59543.875
+$ arttime --datetime_utc=2021-11-25T21:00:00 
+$ arttime --datetime_msk=2021-11-26T00:00:00 
+```
+
+Available parameters:
+
++ --artday (--aday)         - ART-XC days
++ --missiontime (--mtime)   - Mission time - onboard ART-XC seconds
++ --mjd                     - MJD
++ --datetime_utc (--dt_utc) - Date time based on UTC time zone
++ --datetime_msk (--dt_msk) - Date time based on Moscow time zone (UTC+3)
