stringToPosix("2016-05-26")
#> [1] "2016-05-26 UTC"
stringToPosix("2016-05-26 12:00")
#> [1] "2016-05-26 12:00:00 UTC"
  
# additional arguments passed to hsToPosix
stringToPosix("2016-05-26 12:00:33", tzone = "ETC/Gmt-1")
#> [1] "2016-05-26 12:00:33 +01"
  
# lt = TRUE -> create POSIXlt instead of POSIXct
lt1 <- stringToPosix("2016-05-26 17:00", lt = TRUE)
lt2 <- stringToPosix("2016-05-26 17:00", lt = TRUE, tz = "Europe/Berlin")
  
lt1$hour
#> [1] 17
lt1$isdst # normal time (is daylight saving time = FALSE)
#> [1] 0
lt2$isdst # summer time (is daylight saving time = TRUE)
#> [1] 1
