| - | WinSCP automatically resolves ''%TIMESTAMP%'' to a real time with format ''20141024161712''.((Unless the ''%TIMESTAMP%'' variable is already set in an environment, when WinSCP is started.)) | + | WinSCP automatically resolves ''%TIMESTAMP[rel]#format%'' to a real time (optionally to a past or future time) with the given format. The ''format'' may include ''yyyy'' for year, ''mm'' for month, ''dd'' for day, ''hh'' for hour, ''nn'' for minute and ''ss'' for second. For example, the ''%TIMESTAMP#yyyy-mm-dd%'' resolves to ''2016-06-22'' on 22 June 2016. See [[https://docwiki.embarcadero.com/Libraries/en/System.SysUtils.FormatDateTime|other formats you can use]]. |
| - | You can customize the format using syntax ''%TIMESTAMP#format%'' where ''format'' may include ''yyyy'' for year, ''mm'' for month, ''dd'' for day, ''hh'' for hour, ''nn'' for minute and ''ss'' for second. For example ''%TIMESTAMP#yyyy-mm-dd%'' resolves to ''2014-10-24''.((Syntax ''%TIMESTAMP#format%'' is resolved by WinSCP to a real time, even if ''%TIMESTAMP%'' variable is already set in environment, when WinSCP is started.)) See [[http://docwiki.embarcadero.com/Libraries/XE6/en/System.SysUtils.FormatDateTime|other formats you can use]]. | + | The optional ''rel'' part, with syntax ''[-+]time[YDHNS]'', produces past (''-'') or future (''+'') timestamps. One of the following units must be used: ''Y'' (years), ''D'' (days), ''H'' (hours), ''N'' (minutes) or ''S'' (seconds). For example, the ''%TIMESTAMP-1D#yyyy-mm-dd%'' (the ''-1D'' meaning one day in the past) resolves to ''2016-06-21'' on 22 June 2016. |

| - | If you are going to run the script under a different account (for example using the Windows scheduler), don't forget that WinSCP still needs to access its configuration. Note that when using registry as [[config|configuration storage]], the settings are accessible only for your Windows account, so in such a case you may need to either transfer the configuration from your account registry to the other account's registry or use the [[config|INI file]] instead. | + | If you are going to run the script under a different account (for example [[guide_schedule|using the Windows Task Scheduler]]), make sure the script does not rely on a configuration settings that might differ on the other account. When using registry as [[config|configuration storage]], the settings are accessible only for your Windows account. Ideally, make sure the script does not rely on any external configuration, to make it completely portable. Note that the configuration also includes [[#hostkey|verified SSH host keys]] and FTPS/WebDAVS [[tls#certificate|TLS/SSL certificates]]. |

| ===== [[configuration]] Sharing Configuration with Graphical Mode ===== | ===== [[configuration]] Sharing Configuration with Graphical Mode ===== | ||
| - | WinSCP in scripting/console mode shares [[config|configuration]] with [[interfaces|graphical mode]]. This can be both advantageous and disadvantageous. | + | In scripting/console mode, WinSCP shares [[config|configuration]] with [[interfaces|graphical mode]] by default. While this can be useful in some cases, it can also be a disadvantage. |
| - | The advantage is that you can use graphical interface to [[faq_script_ini|configure options for which there are no script commands]]. | + | The disadvantage is that change to configuration in graphical mode may break your script (common example is enabling //[[ui_synchronize|Existing files only]]// option for [[task_synchronize_full|synchronization]]). Also the script is not portable to other machines, when it relies on an external configuration. |
| - | The disadvantage is that change to configuration in graphical mode may break your script (common example is enabling //[[ui_synchronize|Existing files only]]// option for [[task_synchronize_full|synchronization]]). | + | If you want to protect your script from such inadvertent change or if you want to make the script portable, you should isolate its configuration from graphical mode explicitly. |
| - | If you want to protect your script from such inadvertent change, you should isolate its configuration from graphical mode explicitly. | + | The best way to do that is to configure all the options you need using script commands only (''[[scriptcommand_option|option]]'' command, switches of other commands, [[session_url|session URL]]), or if no such command is available, using [[rawsettings|raw site settings]] and [[rawconfig|raw configuration]]. Finally force scripting mode to [[config#no|start with the default configuration]] using ''[[commandline#configuration|/ini=nul]]'' command-line parameter. |

Finally force scripting mode to start with the default configuration using ''/ini=nul'' [[commandline|command-line parameter]]. | + | Alternatively [[config#export|export your configuration]] to a separate INI file and reference it using ''[[commandline#configuration|/ini=]]'' command-line parameter. Also consider setting the INI file read-only, to prevent WinSCP writing to it, when exiting. Particularly, if you are running multiple scripts in parallel, to prevent different instances of WinSCP trying to write it at the same time. |
