are:

     time    An ascii time/date string
     t_ref   an on-board time in TAI seconds in the SOHO epoch
     hour    an integer hour of mission, SOI epoch 1993.01.01
     six     an integer 6-hour interval of mission, SOI epoch 1993.01.01
     day     an integer day of mission, SOI epoch 1993.01.01
     thirty  an integer 30-day interval of mission, SOI epoch 1993.01.01

Only

one

time

is

done

for

each

of

time_index.

The

time

-k Print the kind as "time" "t_ref" "day" or "hour"

-t Print the time as a string date.

-h Print the time as hour of mission, SOI epoch

-6 Print the time as six_hour interval.

-d Print the time as day of mission, SOI epoch

-3 Print the time as 30-day interval.

-r Print the time as a t_ref in seconds SOHO epoch

-a Print all info in the order -k -t -h -d -r -6 -3
