EPOCHREALTIME

[hancooper]

Have been using $EPOCHREALTIME but can see that the output is as follows.

1629376497,853634

The utilisation of tho comma `,` is very inconvenient for those who want to do 
time
computations. A change towards a period `.` would be the proper way to display 
the
variable.

Furthermore, one gets nanosecond precision when using date. But such precision
is not possible with EPOCHREALTIME. Thusly, the improvement to nanosecond

precision is desirable so as to match the capability of data.
