convert_UTC_to_localtime: Convert time from UTC to local time.

In USGS-R/streamMetabolizer: Models for Estimating Aquatic Photosynthesis and Respiration

Convert time from UTC to local time.

Description

Convert time from UTC to local time, either standard or with daylight savings. Recommended for post-analysis visualization only; most functions in streamMetabolizer use times in UTC. If you know the timezone code for your local site, use with_tz instead.

Usage

convert_UTC_to_localtime(
  date.time,
  latitude,
  longitude,
  time.type = c("standard local", "daylight local")
)

Arguments

date.time	POSIXct object the date and time in UTC
latitude	numeric, in degrees, either positive and unitted ("degN" or "degS") or with sign indicating direction (positive = North)
longitude	numeric, in degrees, either positive and unitted ("degE" or "degW") or with sign indicating direction (positive = East)
time.type	character. The type of time zone desired - either standard time without any daylight savings time or daylight time where daylight savings is on during the appropriate days
