If you look at the as_datetime function, under the ‘format’ section there is a link to the strptime documentation

?lubridate::as_datetime

If you look at the strptime documentation, you will get a nice table of codes you can use to create your own datetime pattern

?strptime

You can now use these variables to create a pattern for your custom datetime string

curr_time <- lubridate::as_datetime('WED 06-JUNE-18 10:47:30 AM',
                       format = '%a %d-%B-%y %I:%M:%S %p',
                       tz = "EST")
curr_time
