Get Formatted Date From Timestamp With Rounded Milliseconds Bash Shell Script


bash date timestamp

You may simply use %3N to truncate the nanoseconds to the 3 most significant digits:

$ date +"%Y-%m-%d %H:%M:%S,%3N"2014-01-08 16:00:12,746

or

$ date +"%F %T,%3N"2014-01-08 16:00:12,746

testet with »GNU bash, Version 4.2.25(1)-release (i686-pc-linux-gnu)«

But be aware, that %N may not implemented depending on your target system or bash version.Tested on an embedded system »GNU bash, version 4.2.37(2)-release (arm-buildroot-linux-gnueabi)« there was no %N:

date +"%F %T,%N"2014-01-08 16:44:47,%N

Million ways to do this.. one simple way is to remove the trailing numbers...

date +'%Y-%m-%d %H:%M:%S.%N' | sed 's/[0-9][0-9][0-9][0-9][0-9][0-9]$//g'

or

date +'%Y-%m-%d %H:%M:%S.%N' | sed 's/......$//g'

bash date timestamp

I can't help offering a "cheap" solution...

echo $(date +"%Y-%m-%d-%H:%M:%S.")$((RANDOM%1000))

After all, if accuracy is less important than uniqueness, as it is in my case... here you have it.
