Sorry there is no way in .NET to change the time zone globally. The only way you have is to change the timezone of your server or rewrite all of your code. The best practice is to not rely on the system time zone at all (never use DateTime.Now). You should handle all date as … Read more
You could use pd.to_datetime: In [1]: import pandas as pd In [2]: pd.to_datetime(‘2008-02-27’) Out[2]: datetime.datetime(2008, 2, 27, 0, 0) This allows you to “clean” the index (or similarly a column) by applying it to the Series: df.index = pd.to_datetime(df.index) or df[‘date_col’] = df[‘date_col’].apply(pd.to_datetime)
Can someone explain how Date.UTC works Date.UTC creates a timevalue for the provided year, month, date, etc. without any offset. So if the client machine is set for, say, UTC +05:00 then: var d = new Date(Date.UTC(2013, 11, 30, 12, 0, 0)); will create a date equivalent to noon on 30 December 2013 at Greenwich. … Read more
The key is to switch the local timezone to the desired display timezone, for the duration of the transaction: begin; set local timezone to ‘EST5EDT’; select to_char(‘2012-05-29 15:00:00’::timestamp at time zone ‘CDT’, ‘YYYY-MM-DD HH24:MI:SS TZ’); end; The result is: 2012-05-29 16:00:00 EDT Note that with set [local] timezone it is required to use full time … Read more
Be careful about leap years in your daysInMonth function. If you want very high performance, you can precompute the pair to get to month+year in one step, and then calculate the day/hour/min/sec. A good solution is the one in the gmtime source code: /* * gmtime – convert the calendar time into broken down time … Read more
I found this solution which solves the whole thing quite elegantly I think (not my code): import datetime YEAR_CHOICES = [] for r in range(1980, (datetime.datetime.now().year+1)): YEAR_CHOICES.append((r,r)) year = models.IntegerField(_(‘year’), choices=YEAR_CHOICES, default=datetime.datetime.now().year) Edit the range start to extend the list 🙂
Use PreparedStatement#setTimestamp() wherein you pass a java.sql.Timestamp which is constructed with System#currentTimeMillis(). preparedStatement.setTimestamp(index, new Timestamp(System.currentTimeMillis())); // … Alternativaly, if the DB supports it, you could also call a DB specific function to set it with the current timestamp. For example MySQL supports now() for this. E.g. String sql = “INSERT INTO user (email, creationdate) VALUES … Read more
If you have a Series like: In [116]: df[“Date”] Out[116]: 0 2012-10-08 07:12:22 1 2012-10-08 09:14:00 2 2012-10-08 09:15:00 3 2012-10-08 09:15:01 4 2012-10-08 09:15:01.500000 5 2012-10-08 09:15:02 6 2012-10-08 09:15:02.500000 7 2012-10-10 07:19:30 8 2012-10-10 09:14:00 9 2012-10-10 09:15:00 10 2012-10-10 09:15:01 11 2012-10-10 09:15:01.500000 12 2012-10-10 09:15:02 Name: Date where each object is … Read more
