Timestamp

The pygmt.Figure.timestamp method can draw the GMT timestamp logo on the plot. The timestamp will always be shown relative to the bottom-left corner of the plot. By default, the offset and justify parameters are set to ("-54p", "-54p") (x, y directions) and "BL" (bottom-left), respectively.

import os

import pygmt

fig = pygmt.Figure()
fig.basemap(region=[20, 30, -10, 10], projection="X10c/5c", frame=True)
fig.timestamp()
fig.show()

Additionally, a custom label can be added via the label parameter. The font can be defined via the font parameter and the timestamp string format via timefmt.

os.environ["TZ"] = "Pacific/Honolulu"  # optionally set the time zone

fig = pygmt.Figure()
fig.coast(region="d", projection="H10c", land="black", water="cornsilk", frame="afg")
fig.timestamp(
    label="Powered by PyGMT",
    justify="TL",
    font="Times-Bold",
    timefmt="%Y-%m-%dT%H:%M:%S%z",
)
fig.show()
