j2posix {RSEIS} | R Documentation

## Convert RSEIS date list to Posix

### Description

Convert RSEIS date list to a cmpatable date/time for calculating dates and times with base R codes.

### Usage

    j2posix(timeinput)

### Arguments

`timeinput` | RSEIS date-time list

### Details

Code here converts to posix, but works only down to the second, i.e. fractions of a second are dropped.

### Value

POSIX compatable date time structure.

### Note

If you need to preserve the fractional seconds (as we do in seismology) it is recommended to cut them off and add them later.
