从字符串生成时间戳

from datetime import datetime

# 示例字符串
time_str = "2023-10-05 14:30:00"

# 将字符串转换为datetime对象
dt_obj = datetime.strptime(time_str, "%Y-%m-%d %H:%M:%S")

# 将datetime对象转换为UNIX时间戳（秒）
timestamp = dt_obj.timestamp()

print(f"时间戳: {timestamp}")

time_str = "2023/10/05 14:30:00"
dt_obj = datetime.strptime(time_str, "%Y/%m/%d %H:%M:%S")
timestamp = dt_obj.timestamp()
print(f"时间戳: {timestamp}")

import pytz
from datetime import datetime

time_str = "2023-10-05 14:30:00"
dt_obj = datetime.strptime(time_str, "%Y-%m-%d %H:%M:%S")
dt_obj = dt_obj.replace(tzinfo=pytz.utc)
timestamp = dt_obj.timestamp()
print(f"UTC时间戳: {timestamp}")
